Rank

sage: E.rank()

The elliptic curves in class 4026.d have rank \(0\).

Modular form 4026.2.a.d

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

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 LMFDB numbering.

\(\left(\begin{array}{rr} 1 & 2 \\ 2 & 1 \end{array}\right)\)

Isogeny graph

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

The vertices are labelled with LMFDB labels.
