Chaque arbre binaire est associé à une permutation avec des répétitions qui le détermine uniquement. Deux opérations sont introduites construire l'ensemble de tous les arbres binaires. L'ensemble de toutes les permutations qui correspondent à un arbre binaire donné est déterminé et son nombre cardinal est évalué.

Every binary tree is associated to a permutation with repetitions, which determines it uniquely. Two operations are introduced and used for the construction of the set of all binary trees. The set of all permutations which correspond to a given binary tree is determined and its cardinal number is evaluated.
