Sep 24, 2014 at 3:07 comment added David Loeffler The question you ask in your comment is more philosophical than mathematical: the set of orbits is what it is; what you consider to be an "interpretation" of this set is up to you. :-) I don't know of any particularly nice way of thinking about this set.
Sep 23, 2014 at 11:51 comment added user58510 Is there a way to interpret the $\Gamma$-orbits of bases of $N$-torsion? For example, in the usual case, if the non-split Cartan changes to upper triangular, we will get $X_0(N)$, and each orbit correspond to a cyclic subgroup of order $N$.
