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.
