%0 Journal Article %T Variants of Schroeder Dissections %A Leonard M. Smiley %J Mathematics %D 1999 %I arXiv %X Some formulae are given for the enumeration of certain types of dissections of the convex (n+2)-gon by non-crossing diagonals. The classical Schroeder and Motzkin numbers are addressed using a cataloguing tool, the "reversive symbol". The elementary details are referred to three Web addresses. %U http://arxiv.org/abs/math/9907057v1
