Rank
sage: E.rank()
The elliptic curves in class 960.l have rank \(0\).
Complex multiplication
The elliptic curves in class 960.l do not have complex multiplication.Modular form 960.2.a.l
sage: E.q_eigenform(10)
Isogeny matrix
sage: E.isogeny_class().matrix()
The \(i,j\) entry is the smallest degree of a cyclic isogeny between the \(i\)-th and \(j\)-th curve in the isogeny class, in the LMFDB numbering.
