Rank
sage: E.rank()
The elliptic curves in class 585f have rank \(1\).
Complex multiplication
The elliptic curves in class 585f do not have complex multiplication.Modular form 585.2.a.f
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.
