Hi, I'd like to present Lenstra's elliptic curve factoring method to a class. This means that I'd like to define an elliptic curve over Integers(N), where N is composite, and then add points on that curve in sage. I may be doing something stupid, but I'm getting a NotImplementedError with the method I'm using:
sage: E=EllipticCurve([0,Mod(1,59)]); E Elliptic Curve defined by y^2 = x^3 + 1 over Ring of integers modulo 59 sage: E([0,1]) (0 : 1 : 1) sage: E=EllipticCurve([0,Mod(1,5963)]); E Elliptic Curve defined by y^2 = x^3 + 1 over Ring of integers modulo 5963 sage: E([0,1]) Traceback (most recent call last): ... NotImplementedError Is there a workaround? Does an alternative approach allow the desired computations? Thanks much in advance!
