## On the Relation Between Double Summations and Tetrahedral Numbers

**Authors:** Marco Ripà

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.
