%0 Journal Article %T Restricted Dumont permutations %A Alexander Burstein %J Mathematics %D 2004 %I arXiv %X We analyze the structure and enumerate Dumont permutations of the first and second kinds avoiding certain patterns or sets of patterns of length 3 and 4. Some cardinalities are given by Catalan numbers, powers of 2, little Schroeder numbers, and other known or related sequences. %U http://arxiv.org/abs/math/0402378v1
