Rank
sage: E.rank()
The elliptic curves in class 36963e have rank \(0\).
Complex multiplication
Each elliptic curve in class 36963e has complex multiplication by an order in the imaginary quadratic field \(\Q(\sqrt{-3}) \).Modular form 36963.2.a.e
sage: E.q_eigenform(10)
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.
\(\left(\begin{array}{rrrr} 1 & 3 & 3 & 9 \\ 3 & 1 & 9 & 3 \\ 3 & 9 & 1 & 27 \\ 9 & 3 & 27 & 1 \end{array}\right)\)
Isogeny graph
sage: E.isogeny_graph().plot(edge_labels=True)
The vertices are labelled with Cremona labels.
