## Rank

sage: E.rank()

The elliptic curves in class 2304c have rank $$0$$.

## Complex multiplication

Each elliptic curve in class 2304c has complex multiplication by an order in the imaginary quadratic field $$\Q(\sqrt{-2})$$.

## Modular form2304.2.a.c

sage: E.q_eigenform(10)

$$q + 6 q^{11} + 6 q^{17} - 2 q^{19} + O(q^{20})$$

## 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.
