\\ Pari/GP code for working with elliptic curve 4.4.9909.1-21.1-d2

\\ (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, -3, -6, 0, 1]));

\\ Define the curve: 
E = ellinit([Polrev([2,-3,-1,1]),Polrev([0,-5,-1,1]),Polrev([1,1,0,0]),Polrev([-1404,2629,506,-544]),Polrev([-33259,61674,14266,-13092])], 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]
