Abstract
We derive an expression for the product of the Pfaffians of two skew-symmetric matrices A and B as a sum of products of the traces of powers of AB and an expression for the inverse matrix A, or equivalently B, as a finite-order polynomial of AB with coefficients depending on the traces of powers of AB.
