\\ Pari/GP code for working with elliptic curve 4.4.8000.1-44.2-c2 \\ (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, 0, -10, 0, 1])); \\ Define the curve: E = ellinit([Polrev([1,1,0,0]),Polrev([3,-2,-1/2,1/2]),Polrev([-3,1,1/2,0]),Polrev([-126,76,18,-21/2]),Polrev([1465,-877,-407/2,121])], 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]
