Rank

sage: E.rank()
 

The elliptic curves in class 68354i have rank \(1\).

Modular form 68354.2.a.f

sage: E.q_eigenform(10)
 
\( q + q^{2} - 3q^{3} + q^{4} - q^{5} - 3q^{6} + q^{7} + q^{8} + 6q^{9} - q^{10} + q^{11} - 3q^{12} + q^{13} + q^{14} + 3q^{15} + q^{16} + 4q^{17} + 6q^{18} + 6q^{19} + O(q^{20}) \)

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.

\(\left(\begin{array}{rr} 1 & 7 \\ 7 & 1 \end{array}\right)\)

Isogeny graph

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

The vertices are labelled with Cremona labels.
