Rank

sage: E.rank()

The elliptic curves in class 67760bt have rank $$0$$.

Modular form 67760.2.a.cd

sage: E.q_eigenform(10)

$$q + 2q^{3} - q^{5} + q^{7} + q^{9} + 4q^{13} - 2q^{15} - 4q^{19} + O(q^{20})$$

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.
