[GAP Forum] Automorphism group

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
