\\ Pari/GP code for working with elliptic curve 4.4.10025.1-20.1-d3 \\ (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([20, 10, -11, -1, 1])); \\ Define the curve: E = ellinit([Polrev([-7,-5/2,3/2,1/2]),Polrev([4,9/2,-1/2,-1/2]),Polrev([-7,-5/2,3/2,1/2]),Polrev([125,113,-29,-17]),Polrev([1462,2563/2,-653/2,-393/2])], 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]
