List of uniform polyhedra by vertex figure
Encyclopedia
There are many relations among the uniform polyhedron
Uniform polyhedron
A uniform polyhedron is a polyhedron which has regular polygons as faces and is vertex-transitive...

.
Some are obtained by truncating the vertices of the regular or quasi-regular polyhedron.
Others share the same vertices and edges as other polyhedron.
The grouping below exhibit some of these relations.

The vertex figure of a polyhedron

The relations can be made apparent by examining the vertex figure
Vertex figure
In geometry a vertex figure is, broadly speaking, the figure exposed when a corner of a polyhedron or polytope is sliced off.-Definitions - theme and variations:...

s.
obtained by listing the faces adjacent to each vertex (remember that for uniform polyhedra all vertices are the same, that is vertex-transitive
Vertex-transitive
In geometry, a polytope is isogonal or vertex-transitive if, loosely speaking, all its vertices are the same...

). For example the cube has
vertex figure 4.4.4 that is three adjacent square faces.
The possible faces are
  • 3 - equilateral triangle
  • 4 - square
  • 5 - regular pentagon
  • 6 - regular hexagon
  • 8 - regular octagon
  • 10 - regular decagon
  • 5/2 - pentagram
  • 8/3 - octagram
  • 10/3 - decagram

Some faces will appear with reverse orientation which is written here as
  • -3 - a triangle with reverse orientation (often written as 3/2)

Others pass through the origin which we write as
  • 6* - hexagon passing through the origin


The Wythoff symbol
Wythoff symbol
In geometry, the Wythoff symbol was first used by Coxeter, Longeut-Higgens and Miller in their enumeration of the uniform polyhedra. It represents a construction by way of Wythoff's construction applied to Schwarz triangles....

 relates the polyhedron to spherical triangles
Spherical trigonometry
Spherical trigonometry is a branch of spherical geometry which deals with polygons on the sphere and the relationships between the sides and the angles...

. Wythoff symbols are written
p|q r, p q|r, p q r| where the spherical triangle has angles π/p,π/q,π/r, the bar indicates the position of the vertices in relation to the triangle.
Johnson (2000) classified uniform polyhedra according to the following:
  1. Regular (regular polygonal vertex figures): pq, Wythoff symbol q|p 2
  2. Quasi-regular (rectangular or ditrigonal vertex figures): p.q.p.q 2|p q, or p.q.p.q.p.q, Wythoff symbol 3|p q
  3. Versi-regular (orthodiagonal vertex figures), p.q*.-p.q*, Wythoff symbol q q|p
  4. Truncated regular (isosceles triangular vertex figures): p.p.q, Wythoff symbol q 2|p
  5. Versi-quasi-regular (dipteroidal vertex figures), p.q.p.r Wythoff symbol q r|p
  6. Quasi-quasi-regular (trapezoidal vertex figures): p*.q.p*.-r q.r|p or p.q*.-p.q* p q r|
  7. Truncated quasi-regular (scalene triangular vertex figures), p.q.r Wythoff symbol p q r|
  8. Snub quasi-regular (pentagonal, hexagonal, or octagonal vertex figures), Wythoff symbol p q r|
  9. Prisms (truncated hosohedra),
  10. Antiprisms and crossed antiprisms (snub dihedra)


The format of each figure follows the same basic pattern
  1. image of polyhedron
  2. name of polyhedron
  3. alternate names (in brackets)
  4. Wythoff symbol
  5. Numbering systems: W - number used by Wenninger in polyhedra models, U - uniform indexing, K - Kaleido indexing, C - numbering used in Coxeter et al. 'Uniform Polyhedra'.
  6. Number of vertices V, edges E, Faces F and number of faces by type.
  7. Euler characteristic χ = V - E + F

The vertex figures are on the left, followed by the Point groups in three dimensions#The seven remaining point groups, either tetrahedral Td, octahedral Oh or icosahedral Ih.

Regular polyhedra and their truncated forms

Column A lists all the regular polyhedra,
column B list their truncated forms.
Regular polyhedra all have vertex figures pr: p.p.p etc. and Whycroft symbol
p|q r. The truncated forms have vertex figure q.q.r (where q=2p and r) and Whycroft p q|r.
