Fórmula de conteo para un dominó de tres caras

Abstract

In this article we obtain a formula that calculates the number of points that is obtained when adding the points of all pieces from a domino game of any size, based on its greatest double piece. Also we found the number of pieces of the mentioned domino. This result is obtained from elementary relations that involve only finite sums. Similar results have been obtained using Combinatorial Theory. Additionally, we study a domino game of three faces of any size and we found a formula that that calculates its number of pieces based on its highest trio.
