\\ Pari/GP code for working with elliptic curve 2.0.4.1-32000.2-l5 \\ (Note that not all these functions may be available, and some may take a long time to execute.) \\ Define the base number field: K = nfinit(Polrev([1, 0, 1])); \\ Define the curve: E = ellinit([Polrev([0,0]),Polrev([0,0]),Polrev([0,0]),Polrev([-561,1252]),Polrev([17988,-6066])], K); \\ Compute the conductor: ellglobalred(E)[1] \\ Compute the norm of the conductor: idealnorm(ellglobalred(E)[1]) \\ Compute the discriminant: E.disc \\ Compute the norm of the discriminant: norm(E.disc) \\ Compute the j-invariant: E.j \\ Compute the torsion subgroup: T = elltors(E); T[2] \\ Compute the order of the torsion subgroup: T[1] \\ Compute the generators of the torsion subgroup: T[3]
