[GAP Forum] Computing number of isomorphism classes of finite group

Dear GAP community,

Given a finite group in GAP, how do I compute the number of
isomorphism classes of subgroups of this group?

I wasn't able to find a function that does it for me. What I could do,
I guess, is to compute representatives of the conjugacy classes of
subgroups of the group and then check all representatives pairwise for
isomorphism. But would that be the GAP way to do it?

Any help is greatly appreciated.

Best,
Moritz
