\\ Pari/GP code for working with elliptic curve 5.5.14641.1-23.5-a4

\\ (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([-1, 3, 3, -4, -1, 1]));

\\ Define the curve: 
E = ellinit([Polrev([-1,-3,1,1,0]),Polrev([-5,-4,5,1,-1]),Polrev([3,1,-4,0,1]),Polrev([-829,1375,-792,-703,247]),Polrev([-11294,30720,-12485,-14884,3387])], 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]
