New issue 1933 by k75715: factor(x**27-x, modulus=3)
http://code.google.com/p/sympy/issues/detail?id=1933

factor(x**27-x, modulus=3)
-x*(1 + x)*(1 - x)*(1 + x + x**2 + x**3 + x**4 + x**5 + x**6 + x**7 + x**8 +
x**9 + x**10 + x**11 + x**12)*(1 - x + x**2 - x**3 + x**4 - x**5 + x**6 -
x**7 + x**8 - x**9 + x**10 - x**11 + x**12)

but in Mathematica
Factor[x^27 - x, Modulus -> 3]
x (1 + x) (2 + x) (1 + 2 x + x^3) (2 + 2 x + x^3) (2 + x^2 + x^3) (2 +
    x + x^2 + x^3) (1 + 2 x + x^2 + x^3) (1 + 2 x^2 + x^3) (1 + x +
   2 x^2 + x^3) (2 + 2 x + 2 x^2 + x^3)

is this a bug or something??
