text: As a general form, the tetrahedron is the ony polyhedron with 4 faces, it is the only polyhedron with 6 edges, and it is the only polyhedron with 4 vertices, and no polyhedron can be built with fewer faces, with fewer edges, or with fewer vertices; that means that any effort to build any nomenclature of polyhedra starting from the smallest number of faces, of edges or of vertices always starts with a tetrahedron.
