The group action framework is just the implementation, you still haven't answered the question that this thread was about: Should permutation actions on nested containers automatically discover one possible action or not. As you said, in the group action framework you can implement either possibility. You can also implement either if you don't use it. In any case, http://trac.sagemath.org/14291 is about hooking up GAP and not creating a framework for group actions. So in the interest of a finite amout of work per ticket, we should probably fall back to only allow explicitly specified group actions (OnPoints/OnTuples etc) there. Once your group action framework is in place it'll be easy enough to hook that up into the orbit method as well. -- You received this message because you are subscribed to the Google Groups "sage-combinat-devel" group.
