The Euler characteristic was classically defined for the surfaces of polyhedra, according to the formula where V, E, and F are respectively the numbers of vertices (corners), edges and faces in the given polyhedron. Any convex polyhedron's surface has Euler characteristic Web4. The Euler characteristic of a polyhedron F + V − E = 2. If we glue n heptagons together we have. F = n. Since two faces meet at each edge. E = 7 n 2. And we must have at least 3 faces meeting at a vertex (unless you want to include degenerate heptagons with straight angles, and are really something with fewer sides) V ≤ 7 n 3. and for any n.
