The Archimedean Anti-Prisms
The infiniate set of semi-regular anti-prisms.
These are regular-based with equilateral trinangular sides. For n
{4,5,6,7,8,...} we obtain
a semi-regular anti-prism whose base is a regular n-gon.
For n = 3 we obtain the regular
octahedron. In these anti-prisms, three equilateral
triangles and an n-gon meet at each vertex.
