This looks pretty nasty: sage: Fx.=GF(2^(4*5)) sage: Ex=EllipticCurve(Fx,[0,0,1,1,1]) sage: Ex.defining_polynomial() x^3 + y^2*z + 0*x*z^2 + 0*y*z^2 + 0*z^3 (note the coefficients of zero). I found this while reviewing #5765 but the above is in a vanilla 3.4.2.alpha0, and it is wrong; though t

A bit more info: on sage.math, it is working fine in sage-2.0, but not in sage-2.10 (or anything later). I realise that quite a bit happened between 2.0 and 2.10, but that's the only 2.*'s that I can run (2.5 and 2.6 complain bitterly when started). Weird. -- Alex Ghitza -- Lecturer in Mathem

OK, here's a much simpler example, which also indicates that it's a problem with finite fields (again, aarrgh): {{{ sage: Fx. = GF(2^15) sage: R. = Fx[] sage: R({(1,2):1})# this works fine x*y^2 sage: Fx. = GF(2^16) sage: R. = Fx[] sage: R({(1,2):1})# this sucks!!! 0*x*y^2 }}} In conclus
