ATLAS: Orthogonal group O10-(2)
Order = 25015379558400 = 220.36.52.7.11.17.
Mult = 1.
Out = 2.
The following information is available for O10-(2):
Standard generators of O10-(2) are a and
b, where a is in class 2A, d is in class 5B, ab
has order 33 and abababb has order 18. The last condition is
equivalent to: ababbbb has order 3.
Standard generators of O10-(2):2 are c and
d, where c is in class 2E, d has order 11 and cd
has order 36.
N.B. The old generators for 010-(2):2 that were here before 20.11.97 are no longer available.

The maximal subgroups of O10−(2) are as follows.
The maximal subgroups of O10−(2):2 are as follows.
A set of generators for the maximal cyclic subgroups of O10-(2) can be obtained
by running this program on the standard
generators. All conjugacy classes can therefore be obtained as suitable
powers of these elements.
These classes are compatible with the Atlas of Brauer Characters.
