## Rank

sage: E.rank()

The elliptic curves in class 18975p have rank $$1$$.

## Modular form 18975.2.a.v

sage: E.q_eigenform(10)

$$q + q^{2} + q^{3} - q^{4} + q^{6} + 2q^{7} - 3q^{8} + q^{9} + q^{11} - q^{12} - 2q^{13} + 2q^{14} - q^{16} + q^{18} + 2q^{19} + O(q^{20})$$

## 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.

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

## Isogeny graph

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

The vertices are labelled with Cremona labels.
