Rank
sage: E.rank()
The elliptic curves in class 208.d have rank .
Complex multiplication
The elliptic curves in class 208.d do not have complex multiplication.Modular form 208.2.a.d
sage: E.q_eigenform(10)
Isogeny matrix
sage: E.isogeny_class().matrix()
The entry is the smallest degree of a cyclic isogeny between the -th and -th curve in the isogeny class, in the LMFDB numbering.
Isogeny graph
sage: E.isogeny_graph().plot(edge_labels=True)
The vertices are labelled with LMFDB labels.
