It does find the Verschiebung for ordinary elliptic curves but not for supersingular elliptic curves.1 It seems that `isogenies_prime_degree` only finds separable isogenies, so it never finds the Frobenius. This is not documented very well. It does find the Verschiebung for ordinary elliptic curves but not for supersingular elliptic curves. 2 2 3 3 Ordinary:
