David gale neighborly and cyclic polytopes
Webthe proper investigation of neighborly polytopes began with the work of Gale [7]. For more information on neighborly polytopes (for example, their important role in the Upper bound theorem), we refer to the books by Grun baum [8], McMullen and Shephard [12], Ziegler [19], Matou sek [10]. There is a widespread impression that there are \many ... Webthe technique of affine Gale diagrams [17, Definition 2.6] will be used. In our terminology on convex polytopes we follow Grunbaum [10]. Cyclic polytopes are the paradigms for neighborly polytopes, and, in a sense to be made precise below, they form the basic building blocs for all neighborly polytopes.
