[GAP Forum] computing orbit

[vipul kakkar]

Dear all
Can I do following in GAP and how:

Let G be a group and X be a set on which G acts, I want to calculate number
of orbits .
for example : Let G be any(finite) group and X the set of all subgroups of G
and G acts on X by conjugation and I want to compute number of orbit w.r.t
this action.

Thanks
