Webvertices = 22, edges = 40, faces = 20. Nonagonal antiprism. vertices = 18, edges = 36, faces = 20. If you do a little counting with the surfaces listed above, you will notice the following: If v is the number of vertices, e is the number of edges, and f is the number of faces, then v – e + f is always equal to two.
WebThen we can get to any polyhedron with a nontriangular face by removing some number of edges from a triangulated one and thus the dimension of the realization space is positive. However, this alone doesn't guarantee that the set of real points is positive dimensional. This point is made in Pak's lectures, e.g. Remark 26.3 and footnote 55 on ...
