Dear Pubbers,
I am a MSc student working on group theory.
Let G be a group and G^\prime \in {PSL(2,7) \times PSL(2,7), PSL(2,8) \times
PSL(2,8), A5\times A5, A6\times A6}, where G^\prime denote the derived subgroup
of G. We also define A = Aut(G^\prime). I need to the all subgroups of index 4
, 9 , 4 and 16 in A, when G^\prime = PSL(2,7) \times PSL(2,7) or PSL(2,8)
\times PSL(2,8) or A5\times A5 or A6\times A6, respectively.
All the best, Sima
