# Oscar code for working with elliptic curve 4.4.18097.1-21.1-a5
# If you have not already loaded the Oscar package, you should type "using Oscar;" before running the code below.
# (Note that not all these functions may be available, and some may take a long time to execute.)


# Define the base number field: 
Qx, x = polynomial_ring(QQ); K, a = number_field(Qx([4, 6, -7, -1, 1]))

# Define the curve: 
E = elliptic_curve([K([3,-5/2,-1/2,1/2]),K([2,-7/2,-1/2,1/2]),K([-2,-5/2,1/2,1/2]),K([-9,-64,2,5]),K([-57,-155,13,9])])

# 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: 
j_invariant(E)
