of Riordan's book. Multinomial inverses The inverse relations used in formulating the binomial transform cited in the previous subsection are generalized to corresponding two-index inverse relations for sequences of two indices, and to multinomial inversion formulas for sequences of indices involving the binomial coefficients in Riordan. In particular, we have the form of a two-index inverse relation given by and the more general form of a multinomial pair of inversion formulas given by Notes References External links Why don't they teach Newton's calculus of 'What comes next?' - Mathologer Generating functions
