## Rank

sage: E.rank()

The elliptic curves in class 6468h have rank $$0$$.

## Modular form6468.2.a.b

sage: E.q_eigenform(10)

$$q - q^{3} - 2q^{5} + q^{9} + q^{11} + 2q^{13} + 2q^{15} - 4q^{17} + 6q^{19} + O(q^{20})$$

## 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.
