Looking at the code of
RepresentativeAction, one finds that the following will happen.Moreover
Apparently nobody has ever tried to use
RepresentativeActionin these two situations.From the viewpoint of #6178, one could get the idea to construct a homomorphism between the groups generated by
gensandacts, respectively, to create a new action in terms ofgensonly, and to use this action to compute theRepresentativeActionresult via an orbit-stabilizer computation, but wouldn't it then make more sense to avoid working with differentgens/acts?I would say that the
gens/actsfeature is not really suitable forRepresentativeAction.The same holds for
Permutation.Having different
gens/actsmakes sense whenever one needs just the action of the generators, like inOrbit.Is there anything besides
Orbitfor which thegens/actsfeature is suitable?
