Starting at the structure of Hirota's bilinear expression for nonlinear integrable partial differential equations F. Lambert and R. Willox (preprint 1989) found a combinatorial relation between the quadratic and cubic parts of a polynomial entering the expression. In this paper the author considers the higher order parts of the polynomial.
