Given an infinity of polygons which form the boundary of a finite number of polyhedra, we shall consider the complex K consisting of the polyhedra, and of the faces, edges and vertices of the polygons. We consider only those cases in which the Eulerian Characteristic N of K is finite. Then if the mean number of sides meeting at a vertex is p, and the mean number of sides of a polygon is q, then
