Enneahedra with 9 vertices: Faces 333 333 455

Steven Dutch, Professor Emeritus, Natural and Applied Sciences, Universityof Wisconsin - Green Bay

These are Schlegel Nets; that is, one face (usually the one with the most edges) hasbeen selected as a base and the polyhedron flattened into a plane within the enclosingpolygon. To help with identifying faces, they are color-coded as follows:

Also, we are only concerned with topologically distinct polyhedra, that is, differingin number or type of faces and vertices. Thus, a triangular prism and a tetrahedron withone vertex truncated are topologically equivalent 5-hedra, a cube and rhombohedron aretopologically equivalent 6-hedra, and so on.
