## Rank

sage: E.rank()

The elliptic curves in class 1200.c have rank $$0$$.

## Complex multiplication

The elliptic curves in class 1200.c do not have complex multiplication.

## Modular form1200.2.a.c

sage: E.q_eigenform(10)

$$q - q^{3} - 3 q^{7} + q^{9} - 2 q^{11} - q^{13} - 2 q^{17} + 5 q^{19} + O(q^{20})$$

## 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 LMFDB numbering.

$$\left(\begin{array}{rr} 1 & 5 \\ 5 & 1 \end{array}\right)$$

## Isogeny graph

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

The vertices are labelled with LMFDB labels.
