Rank

sage: E.rank()
 

The elliptic curves in class 55545q have rank \(0\).

Modular form 55545.2.a.q

sage: E.q_eigenform(10)
 
\( q + q^{3} - 2q^{4} + q^{5} - q^{7} + q^{9} - 2q^{12} - q^{13} + q^{15} + 4q^{16} - 3q^{17} - 2q^{19} + O(q^{20}) \)

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.

\(\left(\begin{array}{rr} 1 & 3 \\ 3 & 1 \end{array}\right)\)

Isogeny graph

sage: E.isogeny_graph().plot(edge_labels=True)
 

The vertices are labelled with Cremona labels.
