Rank

sage: E.rank()
 

The elliptic curves in class 786m have rank \(0\).

Modular form 786.2.a.m

sage: E.q_eigenform(10)
 
\( q + q^{2} + q^{3} + q^{4} + q^{5} + q^{6} + 3q^{7} + q^{8} + q^{9} + q^{10} - 3q^{11} + q^{12} + 4q^{13} + 3q^{14} + q^{15} + q^{16} - 7q^{17} + q^{18} + O(q^{20}) \)

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.

\(\left(\begin{array}{rr} 1 & 5 \\ 5 & 1 \end{array}\right)\)

Isogeny graph

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

The vertices are labelled with Cremona labels.
