 This book contains twentytwo papers presented at the International Conference in Combinatorics, held in Jerusalem in May 1993. The papers describe some of the latest developments in algebraic combinatorics, enumeration, graph and hypergraph theory, combinatorial geometry, and geometry of polytopes and arrangements. The papers are accessible to specialists as well as nonspecialists. Readership Combinatorists, algebraists, and computer scientists. Table of Contents  R. M. Adin  On \(h\)vectors and symmetry
