\\ Pari/GP code for working with elliptic curve 4.4.14272.1-81.1-c1 \\ (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([3, 2, -5, -2, 1])); \\ Define the curve: E = ellinit([Polrev([4,-1,-3,1]),Polrev([0,0,0,0]),Polrev([3,-1,-3,1]),Polrev([43,-3,-79,21]),Polrev([291,0,-480,129])], 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]
