I'll point out that conjugacy classes also support the Elements method.
That makes it easy to get all the subgroups with a one line command:
Flat(List(ConjugacyClassesSubgroups(G), x->Elements(x)));
(I know it's easy, but it seems to be a common question).
Of course, it might be more useful/understandable to use xgap or
Gap.app to draw the Hasse diagram, i.e., the subgroups with their inclusion
relations.
