The Transfer Matrix Method is one of the most useful tools in statistical physics. I will soon show how to extend it to the Umbral Transfer Matrix Method, inspired by Gian-Carlo Rota's incredible insight. But in order to facilitate this phase transition from a finite to an infinite "alphabet", I had to really understand, and implement, the finite case. This article is the result.
