Abstract In this paper we are interested in the automorphism group of the poset B m, n . B m, n constitutes the words obtained from the cyclic word of length n on an alphabet of m letters in by deleting on all possible ways and their natural order. We prove: Résumé: Le but de ce papier est la détermination du groupe d"automorphismes des ordres B m, n . Il s"agit des mots obtenus à partir du mot cyclique de longeur n sur un alphabet de m lettres par suppression successive de lettres et ordonnés naturellement. On prouve: AutB m, n = {S n for 1 ≤ n ≤ m, S 2⊗ S 2m-n for m + 1n ≤ 2m - 1, S 2for 2m ≤n.
