Comment (by ncohen):
Yoooooooooooo !
> this is too ugly, uglier than using a class, or whatever. Actually, I
think it is simply wrong to let groups act on some totally unstructured
arbitrary sh*t, and this is exactly what happens right now with allowing
arbitrary domain elements, for which any relation to the original domain
is lost.
Ahahaha. Deal. Do I remove all support for labels on edges and vertices
from graphs ? I am sooooooooooo eager to `:-P`
> Say, if the domain of a group is {1,2,3,4,{1,2},{2,3}}, the very notion
of the orbit of {1,2} is becoming ambiguous, as in a sane world {1,2} is
a subset of {1,2,3,4}, and not a random label.
Well, in Sage however it is not ambiguous :
{{{
g.orbit(Set([1,2]),action="OnPoints")
g.orbit(Set([1,2]),action="OnSets")
}}}
