It is often useful to consider the group action of a permutation group G acting in the natural way on sets and tuples of the original point set.

it would be nice if somehow we could implement the Orbit and Orbits method of permutation groups to handle these actions as well.
I believe the patch to be quite simple but would like to hear what you guys think and suggest before considering to implement it myself.
