Rank

sage: E.rank()
 

The elliptic curves in class 8470f have rank \(0\).

Modular form 8470.2.a.c

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

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 Cremona numbering.

\(\left(\begin{array}{rrrr} 1 & 2 & 3 & 6 \\ 2 & 1 & 6 & 3 \\ 3 & 6 & 1 & 2 \\ 6 & 3 & 2 & 1 \end{array}\right)\)

Isogeny graph

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

The vertices are labelled with Cremona labels.
