Four Polyhedra Featuring Enneagons
Enneagons are also called nonagons; they are polygons with nine sides. I used Stella 4d to make these four rotating polyhedra, and you may try this program for yourself at http://www.software3d.com/Stella.php.

Tessellation of Triangles and Pentagons
Alternately, this can be seen as a tessellation of hexagons and enneagons. Which do you see?

The C320 Fullerene Polyhedron
The duals of the geodesic domes are polyhedra with hexagonal and pentagonal faces. This particular one has 320 vertices, with those vertices representing carbon atoms. Here is C320 as a polyhedron. The next image shows this molecule as a ballandstick … Continue reading

The Construction of a Zome Model of a 240Atom Fullerene Molecule, In Seven Pictures
You can buy your own Zome at http://www.zometool.com.
A Faceting of the Rhombcuboctahedron
This particular faceting of the rhombcuboctahedron can also be viewed as a cluster of stella octangulae. I made it using Stella 4d, polyhedronmanipulating software you can try, for yourself, at http://www.software3d.com/Stella.php.

The Truncated Stella Octangula
This can also be called the compound of two truncated tetrahedra. This image was created using Stella 4d, which you can try at this website.
