I have a group G on the points [1..n]. I know that for some m<n, G maps the set of points [1..m] to itself. Is there an easy way I can get G only on the points [1..m]?
ActionHomomorphism(G,[1..m],OnPoints,"surjective") gives a homomorphism or simply Action(G,[1..m],OnPoints) gives the group acting on [1..m] Best, Alexander _______________________________________________ Forum mailing list [email protected] http://mail.gap-system.org/mailman/listinfo/forum
