\\ Pari/GP code for working with elliptic curve 6.6.1397493.1-64.1-d4 \\ (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, -6, 3, 10, -3, -3, 1])); \\ Define the curve: E = ellinit([Polrev([1,0,0,0,0,0]),Polrev([4,-6,-11,4,3,-1]),Polrev([0,2,7,-2,-3,1]),Polrev([3,-2,-7,2,3,-1]),Polrev([2,-4,-9,3,3,-1])], K); \\ Compute the conductor: ellglobalred(E)[1] \\ Compute the norm of the conductor: idealnorm(K, 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]
