Universal cycles for permutation classes

Abstract
English
We define a universal cycle for a class of $n$-permutations as a cyclic word in which each element of the class occurs exactly once as an $n$-factor. We give a general result for cyclically closed classes, and then survey the situation when the class is defined as the avoidance class of a set of permutations of length $3$, or of a set of permutations of mixed lengths $3$ and $4$.
French
Nous définissons un cycle universel pour une classe de $n$-permutations comme un mot cyclique dans lequel chaque élément de la classe apparaît une unique fois comme $n$-facteur. Nous donnons un résultat général pour les classes cycliquement closes, et détaillons la situation où la classe de permutations est définie par motifs exclus, avec des motifs de taille $3$, ou bien à la fois des motifs de taille $3$ et de taille $4$.
