Hi folks,
Perhaps someone can give a better answer to the question below? I
haven't explored enough with random matrices and finite fields in Sage

Using Sage 3.3 you can do this:
sage: a, b, c, d = var("a b c d")
sage: expand((a + b + c + d)^4)
d^4 + 4*c*d^3 + 4*b*d^3 + 4*a*d^3 + 6*c^2*d^2 + 12*b*c*d^2 +
