Rank
sage: E.rank()
The elliptic curves in class 7350ck have rank \(0\).
Complex multiplication
The elliptic curves in class 7350ck do not have complex multiplication.Modular form 7350.2.a.ck
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 Cremona numbering.
