Miscellaneous Polyhedra

Here we look at miscellaneous categories of polyhedra. The groups formed are interesting though unrelated.

Deltahedra

Deltahedra are polygons built only from equilateral triangles, and by this definition an infinite number of such solids exist. However if we further limit this to convex polyhedra, then only a limited number of such solids exist. All of these are part of various polyhedra sets, which is how I have ordered them below.
