Comment (by ncohen):
> Can't you typify the domain elements somehow, so that they are
recognised as atoms without this kind of problem? (Or mangle them by some
other means...)
Hmmmmmmmmm.... I have no idea how, an I would hate to have to use the
Parent/Element stuff to do that `:-P`
Well, I guess the best is to do as you first did and to split according to
the value of `action`.
By the way, I noticed in the code source of `Graph.is_edge_transitive` a
trick we could use there :
{{{
"OrbitLength("+str(A._gap_())+",Set(" + str(e) + "),OnSets);"
}}}
If we wrap the lists with a Set, then GAP itself reorders them and there
is nothing to fear when giving sets at Sage level `:-)`
