We also given two methods to determine the curve Z. The first uses interpolation, and also determines the relevant twisting scalar. It can be used to find a Jacobian over QQ that admits a rational 70-torsion point. The second method is more geometrically inspired and exploits the geometry of the Kummer surface of Y.
This is joint work with Jeroen Hanselman and Sam Schiavone.
