Corrections to the ATLAS of Finite Groups
The main list of corrections is published as an appendix to
the `Atlas of Brauer Characters', by C. Jansen, K. Lux, R. Parker and
R. Wilson, Oxford, 1995.
Further errors are listed here:

L2(25). Page 16.
 Last maximal subgroup in G.2_{3} should read
(Q_{8} × 3):2.
 Sz(8). Page 28.

In the `Suzuki' construction, the oval is incorrectly defined: add the extra
condition that when t=0, we have x=y=0.

G2(3). Page 60.
 14dimensional construction, definition of D^{2}:
e_{i} should read 3e_{i}.
 Sz(32). Page 77.

In the `Suzuki' construction, the oval is incorrectly defined: add the extra
condition that when t=0, we have x=y=0.

J3. Page 82.
 The definition of C_{Z} only applies when z is nonzero.
The image of e(0) is e(0).

3D4(2). Page 89.
 Replace top row (but not first column) occurrences of s/4 by its conjugate
in 768 matrix orbit.

G2(4). Page 97.
 Delete `nonedge' from Graph column of maximal subgroups.

O7(3). Page 109.
 In 14th maximal subgroup, replace 2E by 2F.

S6(3). Page 113.
 In 7th maximal subgroup, extensions are split.

R(27). Page 123.

First maximal subgroup has shape 3^{3+3+3}:26 in G and
3^{3+3+3}:26:3 in G.3.

Suz. Page 131.
 In 12th maximal subgroup, the extension is nonsplit: (A_{6} × A_{5})^{ . }2.

O8+(3). Page 140.
 The novelties 2^{7}A_{8} in O8+(3):2_{1} (after
the fusion markers for the 10/11th and 12/13th maximal subgroups)
should be 2^{6}:A_{8}:2 =
2^{6}^{ . }S_{8} (the latter extension being nonsplit).

Fi22. Page 160.
 In the additional 5 columns, on p. 310 of the ABC, the centraliser orders
of 12L, 12M, 12N should be 3456, 1296 and 576 respectively.

Fi22. Page 163.
 The structure of the 2Bnormaliser is (2 ×
2^{1+8}):U_{4}(2):2, and correspondingly H.2 in G.2.

2E6(2). Page 191.

16th maximal subgroup has shape 3^{1+6}:2^{3+6}:3^{2}:2
(so there is no quotient S_{3} x 3).

Page 241.

Outer automorphism group of G_{2}(9) is 4, not 2.
