5-cell Prism

In geometry, a uniform 5-polytope is a five-dimensional uniform polytope. By definition, a uniform 5-polytope is vertex-transitive and constructed from uniform 4-polytope facets.

The complete set of convex uniform 5-polytopes 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 4-polytopes) in his publication ''On the Regular and Semi-Regular Figures in Space of n Dimensions''.
*Convex uniform polytopes:
**1940-1988: The search was expanded systematically by H.S.M. Coxeter in his publication ''Regular and Semi-Regular 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
* Non-convex uniform polytopes:
**1966: Johnson describes two non-convex uniform antiprisms in 5-space in his dissertation.
**2000-2022: Jonathan Bowers and other researchers search for other non-convex uniform 5-polytopes, with a current count of 1294 known uniform 5-polytopes outside infinite families (convex and non-convex), excluding the prisms of the uniform 4-polytopes. The list is not proven complete.

Regular 5-polytopes

Regular 5-polytopes can be represented by the Schläfli symbol , with s 4-polytope facets around each face. There are exactly three such regular polytopes, all convex:

* - 5-simplex
* - 5-cube
* - 5-orthoplex

There are no nonconvex regular polytopes in 5 dimensions or above.

Convex uniform 5-polytopes

There are 104 known convex uniform 5-polytopes, plus a number of infinite families of duoprism prisms, and polygon-polyhedron duoprisms. All except the ''grand antiprism prism'' are based on Wythoff constructions, reflection symmetry generated with Coxeter groups.

Symmetry of uniform 5-polytopes in four dimensions

The 5-simplex is the regular form in the A₅ family. The 5-cube and 5-orthoplex are the regular forms in the B₅ family. The bifurcating graph of the D₅ family contains the 5-orthoplex, as well as a 5-demicube which is an alternated 5-cube.

Each reflective uniform 5-polytope 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 even-branches. Symmetry groups of the form ,b,b,a have an extended symmetry, a,b,b,a, like ,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 5-polytope with chiral symmetry, shown as "empty" circled nodes", but the geometry is not generally adjustable to create uniform solutions.

;Fundamental families

;Uniform prisms

There are 5 finite categorical uniform prismatic families of polytopes based on the nonprismatic uniform 4-polytopes. There is one infinite family of 5-polytopes based on prisms of the uniform duoprisms ××.

;Uniform duoprisms

There are 3 categorical uniform duoprismatic families of polytopes based on Cartesian products of the uniform polyhedra and regular polygons: ×.

Enumerating the convex uniform 5-polytopes

* Simplex family: A₅ ⁴** 19 uniform 5-polytopes
* Hypercube/ Orthoplex family: B₅ ,3³** 31 uniform 5-polytopes
* Demihypercube D₅/E₅ family: ^2,1,1** 23 uniform 5-polytopes (8 unique)
* Polychoral prisms:
** 56 uniform 5-polytope (45 unique) constructions based on prismatic families: ,3,3— nbsp; ,3,3— nbsp; ,3,3— nbsp; ^1,1,1— nbsp;
** One non-Wythoffian - The grand antiprism prism is the only known non-Wythoffian convex uniform 5-polytope, 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 5-polytope constructions based on duoprism prismatic families: 'p''— 'q''— nbsp;
* Infinitely many uniform 5-polytope constructions based on duoprismatic families: ,3— 'p'' ,3— 'p'' ,3— 'p''

The A₅ family

There are 19 forms based on all permutations of the Coxeter diagrams with one or more rings. (16+4-1 cases)

They are named by Norman Johnson from the Wythoff construction operations upon regular 5-simplex (hexateron).

The A₅ 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 5-polytopes with 5-simplex symmetry can be generated as permutations of simple integers in 6-space, all in hyperplanes with normal vector (1,1,1,1,1,1).

The B₅ family

The B₅ family has symmetry of order 3840 (5!×2⁵).

This family has 2⁵−1=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 D₅ 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 5-polytopes 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 5-cube family of 5-polytopes 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 5-polytope. All coordinates correspond with uniform 5-polytopes of edge length 2.

The D₅ family

The D₅ family has symmetry of order 1920 (5! x 2⁴).

This family has 23 Wythoffian uniform polytopes, from ''3×8-1'' permutations of the D₅ Coxeter diagram with one or more rings. 15 (2×8-1) are repeated from the B₅ family and 8 are unique to this family, though even those 8 duplicate the alternations from the B₅ family.

In the 15 repeats, both of the nodes terminating the length-1 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 5-polytopes 20 through 34 above. The 8 new forms have one such node ringed and one not, with the relation ... = ... duplicating uniform 5-polytopes 51 through 58 above.

B₄ × A₁

This prismatic family has 16 forms. (Three are shared with ,4,3— nbsp;family)

The A₁×B₄ family has symmetry of order 768 (2⁵4!).

The last three snubs can be realised with equal-length edges, but turn out nonuniform anyway because some of their 4-faces are not uniform 4-polytopes.

Notes on the Wythoff construction for the uniform 5-polytopes

Construction of the reflective 5-dimensional 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 5-polytopes 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 5-polytopes.

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.

There are three regular honeycombs of Euclidean 4-space:
* tesseractic honeycomb, with symbols {4,3,3,4}, = . There are 19 uniform honeycombs in this family.
* 24-cell honeycomb, with symbols {3,4,3,3}, . There are 31 reflective uniform honeycombs in this family, and one alternated form.
** Truncated 24-cell honeycomb with symbols t{3,4,3,3},
** Snub 24-cell honeycomb, with symbols s{3,4,3,3}, and constructed by four snub 24-cell, one 16-cell, and five 5-cells at each vertex.
* 16-cell honeycomb, with symbols {3,3,4,3},

Other families that generate uniform honeycombs:
* There are 23 uniquely ringed forms, 8 new ones in the 16-cell honeycomb family. With symbols h{4,3²,4} it is geometrically identical to the 16-cell honeycomb, =
* There are 7 uniquely ringed forms from the ${\tilde{A_4$, family, all new, including:
** 4-simplex honeycomb
** Truncated 4-simplex honeycomb
** Omnitruncated 4-simplex honeycomb
* There are 9 uniquely ringed forms in the ${\tilde{D_4$: ^1,1,1,1 family, two new ones, including the quarter tesseractic honeycomb, = , and the bitruncated tesseractic honeycomb, = .

Non-Wythoffian uniform tessellations in 4-space also exist by elongation (inserting layers), and gyration (rotating layers) from these reflective forms.
