11800 Problem with points at infinity in hyperelliptic curves gaudry AlexGhitza "The function that lists the points on a hyperelliptic curve assumes that the point [0, 1, 0] is always valid. This is wrong and creates the following bug:
{{{
sage: R. = GF(7)[]
sage: H = HyperellipticCurve(3*x^2 + 5*x + 1)
sage: H.points()
...
TypeError: Coordinates [0, 1, 0] do not define a point on Hyperelliptic Curve over Finite Field of size 7 defined by y^2 = 3*x^2 + 5*x + 1
