摘 要：
We explore some recent results about Riordan arrays and orthogonal
polynomials, and apply these results to the study of some well-known
combinatorial polynomials and to the enumeration of permutations. In
particular we characterise certain combinatorial polynomials as the
moments of families of orthogonal polynomials. We also apply Riordan
arrays to the study of generalised Catalan numbers.
