Note that there are other interesting actions available from GAP
OnTuples
(for stabilizers, these are simply intersection of action on points)OnSetsSets

There are no rules (yet) about this kind of things :-P

True. To be honest, I did not want to generalize the code from .orbits
(which handles all cases) for only two functions. But then, if a third one needs that, you know... :-P
