5890 [with patch, woth positive review] clean up schemes/elliptic_curves/ell_generic.py AlexGhitza AlexGhitza "As noted at #5765, {{{ell_generic.py}}} has some functions that do not make sense over a general ring and should rather be moved down to {{{ell_field.py}}} or one of its descendants.
Note also William's comment from #5765: I think it would be nice to be able to implement the elliptic curve factorization method (ECM) without having to use this hack:
{{{
R = Zmod(N)
R.is_field = lambda: True
E = EllipticCurve(R, [-1,0])
}}}
