comment Important formulas in Combinatorics
Dear Aryeh, I guess that if one can present nicely an important result in a novel way as a formula, this should be ok, but I worry this will be too inclusive.. Certainly the Sauer-Shelah-Vapnik-Chervonenkis lemma is very fundamental.gilkalai.wordpress.com/2008/09/28/…

Thanks Aryeh, There are three conditions for an answer, it needs to be combinatorics (widely interpreted), it needs to be important, and it needs to be (already) in a form of a formula.

comment Important formulas in Combinatorics
There are several areas of combinatorics that are not yet represented. (Of course it is very natural that enumerative combinatorics has so many wonderful formulas.) Also if you have suggestions to choose from you can always mention them in a comment.

Dear Incnis, Yes it is! Zaslavsky's formula is a very important formula in enumerative combinatorics, as well as geometric combinatorics, and the basis for important developments in topological combinatorics.

In short, Asaf, my answer is YES!
