Combinatorial Sums and Inversions
Combinatorial Sums and Inversions
Traditional methods used for solving combinatorial sums (see, e.g., J. Riordan [18] or L. Comtet [1]) are used in R. L. Graham, D. E. Knuth, and O. Patashnik [8], where it is shown how to use the rules of binomial coefficients, Stirling numbers, and so on, for computing combinatorial sums. …
