On the Relation Between Double Summations and Tetrahedral Numbers

Authors: Marco Ripà
Comments: 3 pages

In this paper we provide an inverse proof of the relation between a particular class of double sums and tetrahedral numbers. Thus, we present a compact formula to reduce the number of calculations necessary to solve such a kind of problems. The initial identity is confirmed �a posteriori� using the formula mentioned above.
