unsigned short number_of_polygon_types  Protected variable 
The number of different types of polygon making up the faces of a
Polyhedron . The Platonic polyhedra have only one type of face,
while the Archimedean can have more.

real face_radius  Protected variable 
The radius of the sphere that touches the centers of the polygonal faces of the polyhedron (Inkugel, in German). 
real edge_radius  Protected variable 
The radius of the sphere that touches the centers of the edges of the polyhedron. 
real vertex_radius  Protected variable 
The radius of the sphere touching the vertices of the polyhedron (Umkugel, in German).
