Modular form1386.2.a.d

sage: E.q_eigenform(10)

$$q - q^{2} + q^{4} + 2 q^{5} - q^{7} - q^{8} - 2 q^{10} - q^{11} - 4 q^{13} + q^{14} + q^{16} + 2 q^{17} - 6 q^{19} + O(q^{20})$$ 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.
