[sage-support] define elliptic curve y^2=x^3-x over finite field 11

2017-06-20 Thread Xavier Nogues
Hello, I dont know how to define elliptic curve y^2=x^3-x over finite field 11. The negative "-x" is the problem p=11 E=EllipticCurve(GF(p),[0,0,0,-1,0]); Elliptic Curve defined by y^2 = x^3 + *10*x* over Finite Field of size 11 Thanks -- You received this message because you are subsc
