Recall that the coefficient of ts is the number of Franklin squares of magic sum s (see [1] or [3]). This information along with [16, Corollary 4.3.1] enables us to recover the Hilbert function F8(J) from the Hilbert-Poincar6series by interpolation. The formulas for the number of 8 x 8 pandiagonal Franklin squares in Theorem 1.3 are derived similarly.
