### Understanding SAGE code

Hey, I want to implement a functionality I found in sage math code into my matlab code, to do so I need to understand what is happening which I really dont, could someone ellaborate and explain the steps? X is apparently creating a GF2 which gives the output x that is in F2 while F is a definition of the X^4+X^3+1? And F_mul somehow ends up with this 0x7f7467c66450 And that I cannot really understand

X = GF(2).polynomial_ring().gen()

F = GF(24, name="a", modulus=X4+X**3+1)

def F_mult(x, y):

return (F.fetch_int(x) * F.fetch_int(y)).integer_representation()


Thanks a bunch!
