The vertices from the triangular face have already been counted. 1 A vertex can be joined to 23 other vertices. Of these, 7 + 6 = 13 lie on the faces of the polyhedron. So each vertex joins to 23 −13 = 10 vertices by diagonals that are internal to the polyhedron. 1

Many of the most studied polyhedra are highly symmetrical, that is, their appearance is unchanged by some reflection or rotation of space. Each such symmetry may change the location of a given vertex, face, or edge, but the set of all vertices (likewise faces, edges) is unchanged. The collection of symmetries of a polyhedron is called its symmetry group. WebPolyhedra 3–13. Outline • linear algebra review • minimal faces and extreme points.
