Dear GAP Forum, I am totally new with GAP and I have a problem as below :
I have a group G:=AutomorphismGroup(PSL(2,9)). One of its Maximal subgroup is $M =N_G(D_8)$. And I would like to computthe order of this group. So I did as follows : > G:=AutomorphismGroup(PSL(2,9)); > H:=DihedralGroup(8); > Normalizer(G,H); But it does not work. I think that somehow I need to "embed" H as a subgroup of G. But I dont know how. Please tell me how I can do. Thanks in advance.
