Abstract
Le problème des rencontres deals with counting derangements of a set with n elements, that is, it deals with the number \(D_{n}\) of permutations of an n-element set without fixed points. Formula for \(D_{n}\) is known for more than 300 years, but it is special because of the variety of ways how to derive it. The main goal of this paper is to present the problem of derangements and offer several interesting proofs of the formula for \(D_{n}\).
Keywords
