Regular[]
All the faces are identical, each edge is identical and each vertex is identical. They all have a Wythoff symbol of the form p|q 2.
Convex[]
The Platonic solids.
|
|
|
|
|
|
Non-convex[]
The Kepler-Poinsot solids.
|
|
|
|
|
Quasi-regular[]
Each edge is identical and each vertex is identical. There are two types of faces which appear in an alternating fashion around each vertex. The first row are semi-regular with 4 faces around each vertex. They have Wythoff symbol 2|p q. The second row are ditrigonal with 6 faces around each vertex. They have Wythoff symbol 3|p q or 3/2|p q.

Wythoff p q|r[]
Truncated regular forms[]
Each vertex has three faces surrounding it, two of which are identical. These all have Wythoff symbols 2 p|q, some are constructed by truncating the regular solids.

Hemipolyhedra[]
The hemipolyhedra all have faces which pass through the origin. Their Wythoff symbols are of the form p p/m|q or p/m p/n|q. With the exception of the tetrahemihexahedron they occur in pairs, and are closely related to the semi-regular polyhedra, like the cuboctohedron.

Rhombic quasi-regular[]
Four faces around the vertex in the pattern p.q.r.q. The name rhombic stems from inserting a square in the cuboctahedron and icosidodecahedron. The Wythoff symbol is of the form p q|r.

Even-sided forms[]
Wythoff p q r|[]
These have three different faces around each vertex, and the vertices do not lie on any plane of symmetry. They have Wythoff symbol p q r|, and vertex figures 2p.2q.2r.
