sage: E.rank()
The elliptic curves in class 74529.t have rank \(0\).
Complex multiplication
Each elliptic curve in class 74529.t has complex multiplication by an order in the imaginary quadratic field \(\Q(\sqrt{-3}) \).Modular form 74529.2.a.t
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 LMFDB numbering.
\(\left(\begin{array}{rr} 1 & 3 \\ 3 & 1 \end{array}\right)\)
Isogeny graph
sage: E.isogeny_graph().plot(edge_labels=True)
The vertices are labelled with LMFDB labels.
