// Magma code for working with elliptic curve isogeny class 228672.cu


// Define the isogeny class: 
E := EllipticCurve([0, 0, 0, -20604, -2670032]);
IsogenousCurves(E);

// Mordell-Weil rank: 
Rank(E);

// q-expansion of modular form: 
ModularForm(E);

// List of curves in the isogeny class: 
IsogenousCurves(E);
