2 now 0<=i<e, 0<=j<d

I'm just curious about the polynomial $\det (x_k^iy_k^j)_{1\leq x_k^iy_k^j)_{0\leq i\leq dd-1, 1\leq 0\leq j\leq ee-1, 1\leq k\leq de}$ (determinant of $de\times de$-matrix, $x_k$, $y_k$ are all independent variables). Is anything known about its factorization on irreducible polynomials?

The question is based only on my own interest.

# Is this polynomial irreducible?
