## Rank

sage: E.rank()

The elliptic curves in class 22050bo have rank $$1$$.

## Modular form 22050.2.a.k

sage: E.q_eigenform(10)

$$q - q^{2} + q^{4} - q^{8} - 3q^{11} - 4q^{13} + q^{16} + 4q^{19} + O(q^{20})$$

## 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.

$$\left(\begin{array}{rr} 1 & 3 \\ 3 & 1 \end{array}\right)$$

## Isogeny graph

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

The vertices are labelled with Cremona labels.
