I have not before now used Sage to count points on hyperelliptic curves over finite fields, only elliptic curves. Am I doing something wrong or is this a bug? It certainly looks like a bug.
sage: F=GF(23) sage: x=polygen(F) sage: C=HyperellipticCurve(x^8+1) sage: C.cardinality() ... ValueError: Q must be a monic polynomial of odd degree >= 3 According to C.count_points_exhaustive() the answer is 24.
