\\ Pari/GP code for working with elliptic curve 3.3.316.1-2.2-a6

\\ (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([2, -4, -1, 1]));

\\ Define the curve: 
E = ellinit([Polrev([1,0,0]),Polrev([2,0,-1]),Polrev([-2,0,1]),Polrev([1688958139908216880,210393969927507918,-397482296655616833]),Polrev([-3609874668113250400329290553,-449683058696981763869697464,849554077046907793046157006])], 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]
