ATLAS: Symplectic group S_{6}(3)
Order = 4585351680 = 2^{9}.3^{9}.5.7.13.
Mult = 2.
Out = 2.
Standard generators of S6(3) are a and b where
a is in class 2A, b has order 5, ab has order 13
and abb has order 14.
Standard generators of the double cover 2.S6(3) are preimages A
and B where B has order 5 and AB has order 13.
Standard generators of S6(3):2 are c and d where c is in
class 2A, d is in class 4F, cd has order 20 and
cdd has order 8.
Standard generators of either 2.S6(3).2 are preimages C and D
where CDCDCDCDDCDDD has order 13.
WARNING: The standard generators in v2.0 for S6(3):2 and 2.S6(3).2 were defined on 27.06.00. The representations in v2.0 for S6(3):2 and 2.S6(3).2 are in these standard generators. There are [or were] no standard generators in v1 for S6(3):2 or 2.S6(3).2. The reprsentations of S6(3):2 and 2.S6(3).2 in v1 are NOT in standard generators as we have defined them above.
