\\ Pari/GP code for working with elliptic curve 5.5.24217.1-61.2-a1 \\ (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, 3, -1, -5, 0, 1])); \\ Define the curve: E = ellinit([Polrev([3,3,-9,-1,2]),Polrev([4,-1,-10,0,2]),Polrev([-2,1,1,0,0]),Polrev([9,6,-20,-2,4]),Polrev([4,9,-7,-4,2])], 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]
