// Magma code for working with elliptic curve 5.5.161121.1-3.1-b4

// (Note that not all these functions may be available, and some may take a long time to execute.)

// Define the base number field: 
R<x> := PolynomialRing(Rationals()); K<a> := NumberField(R![1, 5, 3, -6, -1, 1]);

// Define the curve: 
E := EllipticCurve([K![-6,-10,11,3,-2],K![-2,-6,0,1,0],K![0,-5,0,1,0],K![1790,6565,-5889,-1723,1135],K![47655,157332,-139745,-41489,26992]]);

// Compute the conductor: 
Conductor(E);

// Compute the norm of the conductor: 
Norm(Conductor(E));

// Compute the discriminant: 
Discriminant(E);

// Compute the norm of the discriminant: 
Norm(Discriminant(E));

// Compute the j-invariant: 
jInvariant(E);

// Test for Complex Multiplication: 
HasComplexMultiplication(E);

// Compute the Mordell-Weil rank: 
Rank(E);

// Compute the generators (of infinite order): 
gens := [P:P in Generators(E)|Order(P) eq 0]; gens;

// Compute the heights of the generators (of infinite order): 
[Height(P):P in gens];

// Compute the regulator: 
Regulator(gens);

// Compute the torsion subgroup: 
T,piT := TorsionSubgroup(E); Invariants(T);

// Compute the order of the torsion subgroup: 
Order(T);

// Compute the generators of the torsion subgroup: 
[piT(P) : P in Generators(T)];

// Compute the local reduction data at primes of bad reduction:
