\\ Pari/GP code for working with elliptic curve 3.3.1620.1-9.1-d1

\\ (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([-14, -12, 0, 1]));

\\ Define the curve: 
E = ellinit([Polrev([-8,-1,1]),Polrev([9,2,-1]),Polrev([-7,-2,1]),Polrev([-571008313289912,-78906195919453,56729977251067]),Polrev([-4120565719744519744118,-569409306699890861898,409380059758053249511])], 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]
