Abstract :The Catalan numbers show up in a diverse variety of counting problems. In this note we give yet another characterization of the Catalan number C(n). It is characterized as the dimension of a certain space of multilinear polynomials by exhibiting a basis.Keywords : Catalan numbers, stack-sortable permutations, permutations acting on polynomials.
