Rank

sage: E.rank()
 

The elliptic curves in class 25872.bs have rank \(0\).

Modular form 25872.2.a.bs

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

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 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.
