%C A Mealy model is an even integer combinatorial model on a finite symbol base using a mapping of prime differences.

%C A type of cycling model for sequence based on the Mealy model for sequential machines: the function f is the memory element as a mapping and the Binomial is the combinatorial part. It is called a Mealy machine. Other mapping functions can be used in this general model for an n symbol cycle.
