In this paper, we examine the class of "deco" polyominoes and the succession
rule describing their construction. These polyominoes are enumerated according to their directed height by
factorial numbers. By changing some aspects of the "factorial" rule, we
obtain some succession rules that describe various "deco"
polyomino subclasses.
By enumerating the subclasses according to their height and width, we find
the following well-known numbers: Stirling numbers of the first and second
kind, Narayana and odd index Fibonacci numbers. We wish to point out how the
changes made on the original succession rule yield some new
succession rules that produce transcendental, algebraic and rational
generating functions.
