sage: E.rank()

The elliptic curves in class 55473l have rank $$0$$.

## Modular form 55473.2.a.n

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

## 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.

$$\left(\begin{array}{rrrr} 1 & 2 & 4 & 4 \\ 2 & 1 & 2 & 2 \\ 4 & 2 & 1 & 4 \\ 4 & 2 & 4 & 1 \end{array}\right)$$

## Isogeny graph

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

The vertices are labelled with Cremona labels.
