Hi,
I need to compute the 2-closure of faithful transitive permutation
representations of some sporadic finite simple groups in GAP. My program is:
>G:=SimpleGroup("J1");#for example
>Iso:=IsomorphismPermGroup(G);
>G:=Image(Iso);
>C:=ConjugacyClassesSubgroups(G);
>H:=Representative(c[2]);#for example
>A:=Action(G,RightCosets(G,H),OnRight);
>G2:=TwoClosure(A);
Then I deal with "exceed memory" output"!!! and "return;" also does not
work. I do my computations by a super computer.
What is the problem? How can solve it?
Thank you.
