Look at the output of `factor??`. A ring argument is not supported. So you
have to create the ring first (var gives you only the symbolic ring). Then
create the

The second argument is simply ignored here, by
Is it possible to factor polynomials completely over modular ring?
Like
x = var('x')
factor(x^5-x, IntegerModRing(25)['x'])
gives
(x-1)*(x+1)*(x^2+1)*x
but the actual factorization is x*(x-1)*(x+1)*(x-7)*(x+7)
