## Rank

sage: E.rank()

The elliptic curves in class 834.g have rank $$1$$.

## Modular form834.2.a.g

sage: E.q_eigenform(10)
$$q + q^{2} + q^{3} + q^{4} - 4q^{5} + q^{6} - 2q^{7} + q^{8} + q^{9} - 4q^{10} - 3q^{11} + q^{12} - q^{13} - 2q^{14} - 4q^{15} + q^{16} - 7q^{17} + q^{18} - 5q^{19} + O(q^{20})$$

## 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.

$$\left(\begin{array}{rr} 1 & 5 \\ 5 & 1 \end{array}\right)$$

## Isogeny graph

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

The vertices are labelled with LMFDB labels.
