The application I have in mind is to create an abstract base class for
group homomorphisms of libgap groups. And if we want to compute the
inverse image of a subgroup, then this should be decided by the method
"is_subgroup".
A bit off-topic, but after having group homomorphisms, it will be very
nice to have a method to compute the automorphism group of a group G
which better than:
G._gap_().AutomorphismGroup() or
libgap(G).AutomorphismGroup()
The same goes as to create methods for the inner automorphism group, the
outer automorphism group and the holomorph. One motivation is just
examples in a group theory course, but obviously there many other.
