We have checked that using the simpler monomial does not influence the results in any regime discussed.
He was first to define the monomials x, x 2, x 3,… and 1 / x, 1 / x 2, 1 / x 3,… and to give rules for products of any two of these.
The essence of this method is in finding coefficients of basic monomials via the number of possible arrangements of a graph on a finite linearly ordered set that preserves the order of location of vertices.
