ON THE ENUMERATION OF CONVEX POLYTOPES AND COMBINATORIAL SPHERES.

Abstract

Combinatorial n-spheres and simplicial complexes are equivalent by stellar subdivisions to the boundary of the (n+1) -simplex. Best known examples are the boundary complexes of simplicial (n+1)-polytopes. Despite the obvious relevance of combinatorial n-spheres for topology, for polytopes, for various combinatorial problems, etc., very little is known about them from a combinatorial point of view. The first step in this direction are carried out and lead to some surprising results and to many interesting problems (such as the conjecture that no algorithm inumerates all combinatorial n-spheres).
