Permutations with a prescribed descent set
Résumé
We give a formula to compute the number of permutations with a prescribed descent set in quadratic time. We give the generating function of the number of permutations with a periodic descent set. We introduce an algorithm generating uniformly distributed random permutations with a prescribed descent set.
