In geometry, a uniform 4polytope (or uniform polychoron)^{[1]} is a 4dimensional polytope which is vertextransitive and whose cells are uniform polyhedra, and faces are regular polygons.
There are 47 nonprismatic convex uniform 4polytopes. There are two infinite sets of convex prismatic forms, along with 17 cases arising as prisms of the convex uniform polyhedra. There are also an unknown number of nonconvex star forms.
Regular 4polytopes are a subset of the uniform 4polytopes, which satisfy additional requirements. Regular 4polytopes can be expressed with Schläfli symbol {p,q,r} have cells of type {p,q}, faces of type {p}, edge figures {r}, and vertex figures {q,r}.
The existence of a regular 4polytope {p,q,r} is constrained by the existence of the regular polyhedra {p,q} which becomes cells, and {q,r} which becomes the vertex figure.
Existence as a finite 4polytope is dependent upon an inequality:^{[15]}
The 16 regular 4polytopes, with the property that all cells, faces, edges, and vertices are congruent:

The 24 mirrors of F_{4} can be decomposed into 2 orthogonal D_{4} groups:

The 10 mirrors of B_{3}×A_{1} can be decomposed into orthogonal groups, 4A_{1} and D_{3}:

There are 5 fundamental mirror symmetry point group families in 4dimensions: A_{4} = , B_{4} = , D_{4} = , F_{4} = , H_{4} = .^{[7]} There are also 3 prismatic groups A_{3}A_{1} = , B_{3}A_{1} = , H_{3}A_{1} = , and duoprismatic groups: I_{2}(p)×I_{2}(q) = . Each group defined by a Goursat tetrahedron fundamental domain bounded by mirror planes.
Each reflective uniform 4polytope can be constructed in one or more reflective point group in 4 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,a], have an extended symmetry, [[a,b,a]], doubling the symmetry order. This includes [3,3,3], [3,4,3], and [p,2,p]. 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 4polytope with chiral symmetry, shown as "empty" circled nodes", but the geometry is not generally adjustable to create uniform solutions.

There are 64 convex uniform 4polytopes, including the 6 regular convex 4polytopes, and excluding the infinite sets of the duoprisms and the antiprismatic prisms.
These 64 uniform 4polytopes are indexed below by George Olshevsky. Repeated symmetry forms are indexed in brackets.
In addition to the 64 above, there are 2 infinite prismatic sets that generate all of the remaining convex forms:

The 5cell has diploid pentachoric [3,3,3] symmetry,^{[7]} of order 120, isomorphic to the permutations of five elements, because all pairs of vertices are related in the same way.
Facets (cells) are given, grouped in their Coxeter diagram locations by removing specified nodes.

The three uniform 4polytopes forms marked with an asterisk, *, have the higher extended pentachoric symmetry, of order 240, [[3,3,3]] because the element corresponding to any element of the underlying 5cell can be exchanged with one of those corresponding to an element of its dual. There is one small index subgroup [3,3,3]^{+}, order 60, or its doubling [[3,3,3]]^{+}, order 120, defining an omnisnub 5cell which is listed for completeness, but is not uniform.

This family has diploid hexadecachoric symmetry,^{[7]} [4,3,3], of order 24×16=384: 4!=24 permutations of the four axes, 2^{4}=16 for reflection in each axis. There are 3 small index subgroups, with the first two generate uniform 4polytopes which are also repeated in other families, [1^{+},4,3,3], [4,(3,3)^{+}], and [4,3,3]^{+}, all order 192.

The snub 24cell is repeat to this family for completeness. It is an alternation of the cantitruncated 16cell or truncated 24cell, with the half symmetry group [(3,3)^{+},4]. The truncated octahedral cells become icosahedra. The cubes becomes tetrahedra, and 96 new tetrahedra are created in the gaps from the removed vertices.

This family has diploid icositetrachoric symmetry,^{[7]} [3,4,3], of order 24×48=1152: the 48 symmetries of the octahedron for each of the 24 cells. There are 3 small index subgroups, with the first two isomorphic pairs generating uniform 4polytopes which are also repeated in other families, [3^{+},4,3], [3,4,3^{+}], and [3,4,3]^{+}, all order 576.

This demitesseract family, [3^{1,1,1}], introduces no new uniform 4polytopes, but it is worthy to repeat these alternative constructions. This family has order 12×16=192: 4!/2=12 permutations of the four axes, half as alternated, 2^{4}=16 for reflection in each axis. There is one small index subgroups that generating uniform 4polytopes, [3^{1,1,1}]^{+}, order 96.

When the 3 bifurcated branch nodes are identically ringed, the symmetry can be increased by 6, as [3[3^{1,1,1}]] = [3,4,3], and thus these polytopes are repeated from the 24cell family.

Here again the snub 24cell, with the symmetry group [3^{1,1,1}]^{+} this time, represents an alternated truncation of the truncated 24cell creating 96 new tetrahedra at the position of the deleted vertices. In contrast to its appearance within former groups as partly snubbed 4polytope, only within this symmetry group it has the full analogy to the Kepler snubs, i.e. the snub cube and the snub dodecahedron.
There is one nonWythoffian uniform convex 4polytope, known as the grand antiprism, consisting of 20 pentagonal antiprisms forming two perpendicular rings joined by 300 tetrahedra. It is loosely analogous to the threedimensional antiprisms, which consist of two parallel polygons joined by a band of triangles. Unlike them, however, the grand antiprism is not a member of an infinite family of uniform polytopes.
Its symmetry is the ionic diminished Coxeter group, [[10,2^{+},10]], order 400.

A prismatic polytope is a Cartesian product of two polytopes of lower dimension; familiar examples are the 3dimensional prisms, which are products of a polygon and a line segment. The prismatic uniform 4polytopes consist of two infinite families:
The most obvious family of prismatic 4polytopes is the polyhedral prisms, i.e. products of a polyhedron with a line segment. The cells of such a 4polytopes are two identical uniform polyhedra lying in parallel hyperplanes (the base cells) and a layer of prisms joining them (the lateral cells). This family includes prisms for the 75 nonprismatic uniform polyhedra (of which 18 are convex; one of these, the cubeprism, is listed above as the tesseract).^{[citation needed]}
There are 18 convex polyhedral prisms created from 5 Platonic solids and 13 Archimedean solids as well as for the infinite families of threedimensional prisms and antiprisms.^{[citation needed]} The symmetry number of a polyhedral prism is twice that of the base polyhedron.
This prismatic tetrahedral symmetry is [3,3,2], order 48. There are two index 2 subgroups, [(3,3)^{+},2] and [3,3,2]^{+}, but the second doesn't generate a uniform 4polytope.
