In geometry, a uniform 5polytope is a fivedimensional uniform polytope. By definition, a uniform 5polytope is vertextransitive and constructed from uniform 4polytope facets.
The complete set of convex uniform 5polytopes has not been determined, but many can be made as Wythoff constructions from a small set of symmetry groups. These construction operations are represented by the permutations of rings of the Coxeter diagrams.
History of discovery
 Regular polytopes: (convex faces)
 1852: Ludwig Schläfli proved in his manuscript Theorie der vielfachen Kontinuität that there are exactly 3 regular polytopes in 5 or more dimensions.
 Convex semiregular polytopes: (Various definitions before Coxeter's uniform category)
 1900: Thorold Gosset enumerated the list of nonprismatic semiregular convex polytopes with regular facets (convex regular 4polytopes) in his publication On the Regular and SemiRegular Figures in Space of n Dimensions.^{[1]}
 Convex uniform polytopes:
 19401988: The search was expanded systematically by H.S.M. Coxeter in his publication Regular and SemiRegular Polytopes I, II, and III.
 1966: Norman W. Johnson completed his Ph.D. Dissertation under Coxeter, The Theory of Uniform Polytopes and Honeycombs, University of Toronto
 Nonconvex uniform polytopes:
 1966: Johnson describes two nonconvex uniform antiprisms in 5space in his dissertation.^{[2]}
 20002023: Jonathan Bowers and other researchers search for other nonconvex uniform 5polytopes,^{[3]} with a current count of 1297 known uniform 5polytopes outside infinite families (convex and nonconvex), excluding the prisms of the uniform 4polytopes. The list is not proven complete.^{[4]}^{[5]}
Regular 5polytopes
Regular 5polytopes can be represented by the Schläfli symbol {p,q,r,s}, with s {p,q,r} 4polytope facets around each face. There are exactly three such regular polytopes, all convex:
 {3,3,3,3}  5simplex
 {4,3,3,3}  5cube
 {3,3,3,4}  5orthoplex
There are no nonconvex regular polytopes in 5 dimensions or above.
Convex uniform 5polytopes
Unsolved problem in mathematics: What is the complete set of convex uniform 5polytopes?^{[6]} (more unsolved problems in mathematics)

There are 104 known convex uniform 5polytopes, plus a number of infinite families of duoprism prisms, and polygonpolyhedron duoprisms. All except the grand antiprism prism are based on Wythoff constructions, reflection symmetry generated with Coxeter groups.
Symmetry of uniform 5polytopes in four dimensions
The 5simplex is the regular form in the A_{5} family. The 5cube and 5orthoplex are the regular forms in the B_{5} family. The bifurcating graph of the D_{5} family contains the 5orthoplex, as well as a 5demicube which is an alternated 5cube.
Each reflective uniform 5polytope can be constructed in one or more reflective point group in 5 dimensions by a Wythoff construction, represented by rings around permutations of nodes in a Coxeter diagram. Mirror hyperplanes can be grouped, as seen by colored nodes, separated by evenbranches. Symmetry groups of the form [a,b,b,a], have an extended symmetry, a,b,b,a, like [3,3,3,3], doubling the symmetry order. Uniform polytopes in these group with symmetric rings contain this extended symmetry.
If all mirrors of a given color are unringed (inactive) in a given uniform polytope, it will have a lower symmetry construction by removing all of the inactive mirrors. If all the nodes of a given color are ringed (active), an alternation operation can generate a new 5polytope with chiral symmetry, shown as "empty" circled nodes", but the geometry is not generally adjustable to create uniform solutions.

 One nonWythoffian  The grand antiprism prism is the only known nonWythoffian convex uniform 5polytope, constructed from two grand antiprisms connected by polyhedral prisms.
That brings the tally to: 19+31+8+45+1=104
In addition there are:
 Infinitely many uniform 5polytope constructions based on duoprism prismatic families: [p]×[q]×[ ].
 Infinitely many uniform 5polytope constructions based on duoprismatic families: [3,3]×[p], [4,3]×[p], [5,3]×[p].
The A_{5} family
There are 19 forms based on all permutations of the Coxeter diagrams with one or more rings. (16+41 cases)
They are named by Norman Johnson from the Wythoff construction operations upon regular 5simplex (hexateron).
The A_{5} family has symmetry of order 720 (6 factorial). 7 of the 19 figures, with symmetrically ringed Coxeter diagrams have doubled symmetry, order 1440.
The coordinates of uniform 5polytopes with 5simplex symmetry can be generated as permutations of simple integers in 6space, all in hyperplanes with normal vector (1,1,1,1,1,1).

The B_{5} family
The B_{5} family has symmetry of order 3840 (5!×2^{5}).
This family has 2^{5}−1=31 Wythoffian uniform polytopes generated by marking one or more nodes of the Coxeter diagram. Also added are 8 uniform polytopes generated as alternations with half the symmetry, which form a complete duplicate of the D_{5} family as ... = ..... (There are more alternations that are not listed because they produce only repetitions, as ... = .... and ... = .... These would give a complete duplication of the uniform 5polytopes numbered 20 through 34 with symmetry broken in half.)
For simplicity it is divided into two subgroups, each with 12 forms, and 7 "middle" forms which equally belong in both.
The 5cube family of 5polytopes are given by the convex hulls of the base points listed in the following table, with all permutations of coordinates and sign taken. Each base point generates a distinct uniform 5polytope. All coordinates correspond with uniform 5polytopes of edge length 2.

The D_{5} family
The D_{5} family has symmetry of order 1920 (5! x 2^{4}).
This family has 23 Wythoffian uniform polytopes, from 3×81 permutations of the D_{5} Coxeter diagram with one or more rings. 15 (2×81) are repeated from the B_{5} family and 8 are unique to this family, though even those 8 duplicate the alternations from the B_{5} family.
In the 15 repeats, both of the nodes terminating the length1 branches are ringed, so the two kinds of element are identical and the symmetry doubles: the relations are ... = .... and ... = ..., creating a complete duplication of the uniform 5polytopes 20 through 34 above. The 8 new forms have one such node ringed and one not, with the relation ... = ... duplicating uniform 5polytopes 51 through 58 above.

Notes on the Wythoff construction for the uniform 5polytopes
Construction of the reflective 5dimensional uniform polytopes are done through a Wythoff construction process, and represented through a Coxeter diagram, where each node represents a mirror. Nodes are ringed to imply which mirrors are active. The full set of uniform polytopes generated are based on the unique permutations of ringed nodes. Uniform 5polytopes are named in relation to the regular polytopes in each family. Some families have two regular constructors and thus may have two ways of naming them.
Here are the primary operators available for constructing and naming the uniform 5polytopes.
The last operation, the snub, and more generally the alternation, are the operation that can create nonreflective forms. These are drawn with "hollow rings" at the nodes.
The prismatic forms and bifurcating graphs can use the same truncation indexing notation, but require an explicit numbering system on the nodes for clarity.

Coxeter diagram  Description  

Parent  t_{0}{p,q,r,s}  {p,q,r,s}  Any regular 5polytope  
Rectified  t_{1}{p,q,r,s}  r{p,q,r,s}  The edges are fully truncated into single points. The 5polytope now has the combined faces of the parent and dual.  
Birectified  t_{2}{p,q,r,s}  2r{p,q,r,s}  Birectification reduces faces to points, cells to their duals.  
Trirectified  t_{3}{p,q,r,s}  3r{p,q,r,s}  Trirectification reduces cells to points. (Dual rectification)  
Quadrirectified  t_{4}{p,q,r,s}  4r{p,q,r,s}  Quadrirectification reduces 4faces to points. (Dual)  
Truncated  t_{0,1}{p,q,r,s}  t{p,q,r,s}  Each original vertex is cut off, with a new face filling the gap. Truncation has a degree of freedom, which has one solution that creates a uniform truncated 5polytope. The 5polytope has its original faces doubled in sides, and contains the faces of the dual.  
Cantellated  t_{0,2}{p,q,r,s}  rr{p,q,r,s}  In addition to vertex truncation, each original edge is beveled with new rectangular faces appearing in their place.  
Runcinated  t_{0,3}{p,q,r,s}  Runcination reduces cells and creates new cells at the vertices and edges.  
Stericated  t_{0,4}{p,q,r,s}  2r2r{p,q,r,s}  Sterication reduces facets and creates new facets (hypercells) at the vertices and edges in the gaps. (Same as expansion operation for 5polytopes.)  
Omnitruncated  t_{0,1,2,3,4}{p,q,r,s}  All four operators, truncation, cantellation, runcination, and sterication are applied.  
Half  h{2p,3,q,r}  Alternation, same as  
Cantic  h_{2}{2p,3,q,r}  Same as  
Runcic  h_{3}{2p,3,q,r}  Same as  
Runcicantic  h_{2,3}{2p,3,q,r}  Same as  
Steric  h_{4}{2p,3,q,r}  Same as  
Steriruncic  h_{3,4}{2p,3,q,r}  Same as  
Stericantic  h_{2,4}{2p,3,q,r}  Same as  
Steriruncicantic  h_{2,3,4}{2p,3,q,r}  Same as  
Snub  s{p,2q,r,s}  Alternated truncation  
Snub rectified  sr{p,q,2r,s}  Alternated truncated rectification  
ht_{0,1,2,3}{p,q,r,s}  Alternated runcicantitruncation  
Full snub  ht_{0,1,2,3,4}{p,q,r,s}  Alternated omnitruncation
