Item 1.     Security and Issuer.

            This Statement on Schedule 13D relates to the common stock, $0.01
par value per share (the "WilTel Common Stock"), of WilTel Communications Group,
Inc., a Nevada corporation ("WilTel"). The address of the principal executive
office of WilTel is One Technology Center, Tulsa, OK 74103.

            This Statement is being filed by Leucadia National Corporation
("Leucadia") and its subsidiaries, LUK Acquisition I, LLC ("LUK I") and LUK
Acquisition II, LLC ("LUK II" and collectively with Leucadia and LUK I, the
"Beneficial Owners"). As discussed in Items 3, 4, 5 and 6 below, the Beneficial
Owners are members of a group with respect to the WilTel Common Stock.

            (a)-(c) LUK I is a Delaware limited liability company with its
principal office at c/o Leucadia National Corporation, 315 Park Avenue South,
New York, NY 10010. LUK I was formed to provide a vehicle for Leucadia to make
investments. The sole member of LUK I is Leucadia.

            LUK II is a Delaware limited liability company with its principal
office at c/o Leucadia National Corporation, 315 Park Avenue South, New York, NY
10010. LUK II was formed to provide a vehicle for Leucadia to make investments.
The sole member of LUK II is Leucadia.

            Leucadia is a New York corporation with its principal office at 315
Park Avenue South, New York, New York 10010. Leucadia is a holding company
principally engaged in a variety of businesses, including banking and lending,
property and casualty insurance, manufacturing, winery operations, real estate
activities and development of a copper mine. Approximately 34.8% of the common
shares of Leucadia outstanding at April 11, 2002 (including shares issuable
pursuant to currently exercisable warrants) is beneficially owned (directly and
through family members) by Ian M. Cumming, Chairman of the Board of Directors of
Leucadia, and Joseph S. Steinberg, a director and President of Leucadia
(excluding an additional 2.0% of the common shares of Leucadia beneficially
owned by trusts for the benefit of Mr. Steinberg's children, as to which Mr.
Steinberg disclaims beneficial ownership). Private charitable foundations
independently established by each of Messrs. Cumming and Steinberg each
beneficially own less than one percent of the outstanding common shares of
Leucadia. Mr. Cumming and Mr. Steinberg each disclaim beneficial ownership of
the common shares of Leucadia held by their respective private charitable
foundation. Mr. Cumming and Mr. Steinberg have an oral agreement pursuant to
which they will consult with each other as to the election of a mutually
acceptable Board of Directors of Leucadia.

            The following information with respect to each executive officer and
director of the Beneficial Owners is set forth in Schedule A hereto: (i) name,
(ii) business address, (iii) citizenship, (iv) present principal occupation or
employment and


                                       5

(v) name of any corporation or other organization in which such employment is
conducted.

            (d)-(f) During the last five years, none of the Beneficial Owners
and, to their knowledge, none of the other persons identified pursuant to
Paragraphs (a) through (c) of this Item 2, has been convicted in a criminal
proceeding (excluding traffic violations or similar misdemeanors) or was a party
to a civil proceeding of a judicial or administrative body of competent
jurisdiction as a result of which such person was or is subject to a judgment,
decree or final order enjoining future violations of, or prohibiting or
mandating activities subject to, Federal or State securities laws or finding any
violation with respect to such laws. To the knowledge of the Beneficial Owners,
each of the individuals identified pursuant to Paragraphs (a) through (c) of
this Item 2 is a United States citizen.

Item 3.     Source and Amount of Funds or Other Consideration.

            Pursuant to the Second Amended and Restated Joint Plan of
Reorganization of Williams Communications Group, Inc. ("WCG") and CG Austria
Inc., dated August 12, 2002 (as amended and supplemented, the "Plan") filed by
WCG with the U.S. Bankruptcy Court for the Southern District of New York (the
"Court"), on October 15, 2002, which was the effective date of the Plan (the
"Effective Date"), an aggregate of 22,000,000 shares of WilTel Common Stock (the
"Shares") were issued to the Beneficial Owners (as more fully described below).

            Pursuant to a Purchase and Sale Agreement, dated as of July 26, 2002
between Leucadia and The Williams Companies, Inc. ("TWC") (as amended on October
15, 2002, the "Purchase Agreement"), the Beneficial Owners acquired certain
claims against WCG (the "TWC Assigned Claims") for a purchase price of
$180,000,000 by delivering into escrow pursuant to the Escrow Agreement, dated
as of October 15, 2002, among WilTel, Leucadia, TWC and the Bank of New York, as
Escrow Agent (the "Escrow Agreement"), a letter of credit issued by Fleet Bank
(the "TWC Letter of Credit"). A total of 11,775,000 Shares were received by LUK
I in satisfaction of the TWC Assigned Claims in accordance with the Plan.

            Pursuant to an Investment Agreement, dated as of July 26, 2002 by
and among Leucadia, WCG and Williams Communications, LLC (as amended on
September 16, 2002 and October 15, 2002, the "Investment Agreement"), the
Beneficial Owners purchased 10,225,000 Shares for a purchase price of
approximately $150,000,000 by paying WilTel $1,000 and delivering into escrow
pursuant to the Escrow Agreement, a letter of credit issued by JPMorgan Chase
Bank (the "WilTel Letter of Credit"). A total of 10,225,000 Shares were received
by LUK II in accordance with the Plan.

            Leucadia used its working capital to fund LUK I and LUK II, which in
turn used the capital contributed by Leucadia to collateralize their respective
reimbursement obligations with respect to the TWC Letter of Credit and the
WilTel Letter of Credit. In connection with the issuance of the TWC Letter of
Credit, LUK I entered into a pledge agreement with Fleet Bank pursuant to which
LUK I granted a


                                       6

security interest in, and pledged certain assets to, Fleet Bank. In connection
with the issuance of the WilTel Letter of Credit, LUK II entered into a
collateral agreement with JPMorgan Chase Bank pursuant to which LUK II granted
JPMorgan Chase Bank a security interest in a custody account maintained at
JPMorgan Chase Bank in the name of LUK II.

            The Plan, Purchase Agreement, Investment Agreement and Escrow
Agreement, which are filed as Exhibits to this Schedule 13D, are incorporated
herein by reference.

            The information contained in Item 6 of this Schedule 13D is
incorporated herein by reference.

Item 4.     Purpose of the Transaction.

            Leucadia's purpose in entering into these transactions was to obtain
the opportunity to profit from investing in WilTel and to have significant
influence on the direction of WilTel's business and affairs. The following
description of certain portions of the Plan and the documents implementing the
Plan is qualified in its entirety by reference to (i) the Plan, (ii) the
Investment Agreement, (iii) the Purchase Agreement and (iv) the Escrow
Agreement, each of which is incorporated herein by reference.

            Pursuant to the Plan, on October 15, 2002, Leucadia consummated the
transactions contemplated by the Investment Agreement and the Purchase Agreement
and WilTel issued the Shares.

            Pursuant to the Plan and a Stockholders Agreement dated October 15,
2002 between Leucadia and WilTel (the "Stockholders Agreement"), which is filed
as Exhibit 9 hereto and incorporated herein by reference, Leucadia designated
four (4) members of WilTel's nine (9) member Board of Directors and four (4)
members of the initial reorganized Board of Directors of WilTel were designated
by the Official Committee of Unsecured Creditors of WCG. As a result of the
resignation of the former chief executive officer of WCG, the ninth seat on the
Board of Directors is vacant. The vacancy on the Board of Directors will be
filled in accordance with the Articles of Incorporation of WilTel. The
Stockholders Agreement provides, among other things, that Leucadia is obligated
until the second anniversary of the Effective Date, to vote, and to cause its
subsidiaries to vote, their securities for Committee Independent Directors (as
defined in the Stockholders Agreement) in accordance with the terms of the
Stockholders Agreement. In addition, the Stockholders Agreement provides that
until the fifth anniversary of the Effective Date, Leucadia cannot acquire in
excess of 49% of the issued and outstanding securities of WilTel without the
prior approval of (i) a majority of the Independent Directors (as defined in the
Stockholders Agreement) of WilTel or (ii) the holders of a majority of WilTel's
voting securities that are not owned by Leucadia and its affiliates. The
Stockholders Agreement also gives Leucadia the right to designate (i) four (4)
members of the Board of Directors for as long as Leucadia owns at least twenty
percent (20%) of the WilTel Common Stock and (ii) at least one (1) member of the
Board of Directors for as long as Leucadia owns at least ten percent (10%) of
the WilTel


                                       7

Common Stock. The Stockholders Agreement restricts Leucadia and its affiliates
from (i) commencing any tender or exchange offer for WilTel's voting securities,
(ii) directly or indirectly causing a merger with WilTel following a Permitted
Investor Tender Offer (as defined in the Stockholders Agreement) or (iii)
entering into any transaction between WilTel or its subsidiaries, on the one
hand, and Leucadia or its affiliates, on the other hand. The Stockholders
Agreement is filed as Exhibit 9 hereto, and is incorporated herein by reference.

            As contemplated by the Plan, on the Effective Date, WilTel issued
the Shares to the Beneficial Owners, representing 44% of the equity of WilTel
outstanding as of the Effective Date after giving effect to the WilTel Common
Stock issued pursuant to the Plan, resulting in a total of 50,000,000 shares of
WilTel Common Stock being issued and outstanding as of the Effective Date.

            Pursuant to the Plan, 1,000,000 shares of WilTel Common Stock were
issued on the Effective Date to a securities holder channeling fund pursuant to
a channeling injunction (the "Channeling Injunction") issued by the Court. The
Channeling Injunction enjoins holders of unsecured claims against WCG from
asserting any claims against TWC and their affiliates and against certain
affiliates of WCG for actions taken with respect to WCG on or prior to the
Effective Date. To the extent that the 1,000,000 shares of WilTel Common Stock
are not issued to satisfy such claims, one-half of such unused shares will be
distributed to Leucadia and the other one-half will be distributed to the
holders of unsecured claims against WCG.

            Pursuant to the Plan, the Articles of Incorporation of WilTel
prohibit WilTel from issuing non-voting equity securities. In addition, the
Articles of Incorporation impose certain restrictions on the transfer of
WilTel's equity securities without the prior written approval of WilTel's Board
of Directors. These restrictions are applicable to persons who are or become
(under applicable tax rules) five-percent shareholders of WilTel, without the
prior written approval of WilTel's Board of Directors. However, the Articles of
Incorporation permit Leucadia to acquire up to 49% of the issued and outstanding
shares of WilTel Common Stock without obtaining prior approval from the Board of
Directors. The Articles of Incorporation of WilTel are filed as Exhibit 12
hereto, and are incorporated herein by reference.

            Additional information is included in the responses to Items 3 and 6
of this Schedule 13D, which Items are incorporated herein by reference.

            Subject to and depending upon availability at prices deemed
favorable by Leucadia, Leucadia, directly or through its subsidiaries, may
purchase additional shares of WilTel Common Stock from time to time in the open
market, in privately negotiated transactions with third parties or otherwise,
subject to compliance with the terms of the Stockholders Agreement and the
transfer restrictions contained in WilTel's Articles of Incorporation described
above.


                                       8

            Except as set forth above, the Beneficial Owners have no present
plans or intentions which would result in or relate to any of the transactions
described in subparagraphs (a) through (j) of Item 4 of Schedule 13D.

            (a) As of October 15, 2002, the Beneficial Owners beneficially owned
the following shares of WilTel Common Stock:

                  (i) LUK I is the direct owner of 11,775,000 Shares
representing approximately 23.55% of the 50,000,000 shares of WilTel Common

                  (ii) LUK II is the direct owner of 10,225,000 Shares

                  (iii) By virtue of its ownership of all of the outstanding
membership interests of LUK I and LUK II, for purposes of this Schedule 13D,
Leucadia may be deemed to share voting and dispositive power with respect to the
Shares owned of record by LUK I and LUK II, and therefore may be deemed to be a
beneficial owner of all of the Shares beneficially owned by LUK I and LUK II.

                  (vii) By virtue of their ownership of Leucadia common shares
and their positions with Leucadia, for purposes of this Schedule 13D, Mr.
Cumming and Mr. Steinberg may be deemed to share voting and disposition powers
with respect to the Shares beneficially owned by Leucadia and therefore may be
deemed to be beneficial owners of all of the Shares beneficially owned by
Leucadia.

                  (viii) Except as set forth in Paragraph (i) through (vii) of
this Item 5(a), to the best knowledge of the Beneficial Owners, none of the
other persons identified pursuant to Item 2 above beneficially owns any shares
of WilTel Common Stock.

            (b)   Item 5(a) is incorporated herein by reference.

            (c) Except as otherwise described herein, none of the persons

Common Stock during the past sixty days.

            (d)   Not applicable.

            (e)   Not applicable.

Item 6.     Contracts, Arrangements, Understandings or Relationships with
            Respect to Securities of the Issuer.

            Leucadia has entered into a Registration Rights Agreement with
WilTel by which WilTel has granted Leucadia certain rights to obligate WilTel to
register for sale under the Securities Act of 1933, as amended, the shares of
