\\ Pari/GP code for working with elliptic curve 4.4.8000.1-25.1-b1
\\ (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([0,-3,0,1/2]),Polrev([3,-3,-1/2,1/2]),Polrev([1,-3,0,1/2]),Polrev([38,8,-13,-4]),Polrev([147,51,-105/2,-19])], 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]
