,Une combinatoire non-commutative pour l’etude des nombres secants,inition of various differential and integral operators and different types of substitution operations provides us with the tools and language needed to derive and express many of the laws governing these combinatorial structures.

3D vs. 4D Ontologies in Enterprise Modelingan finally put together a rigorous version of the remaining unexplained portion of Young‘s treatment. This effort has also led us to a remarkably elementary and very combinatorial proof of Pieri‘s rule.

We give a bijective proof of this result. As corollary we give exact formulas for the number of standard Young tableaux having n cells and a most k rows in the cases k=4 and k=5.
