A uniform 5-polytope is a uniform polytope that exists in 5-dimensional Euclidean space. Using a Wythoff construction, the set of uniform 5-polytopes are enumerated below, grouped with the generation symmetry, although there are overlaps as different generators can create the same forms.
Regulars and truncations The three regular 5-polytopes above create 2 families of uniform 5-polytopes. Using a naming scheme proposed by Norman Johnson, these are:
The hexateron family {3,3,3,3}
There are 19 forms:

Uniform alternate truncations
There is a one semiregular polytope from a set of semiregular n-polytopes called a demihypercube, discovered by Thorold Gosset in his complete enumeration of semiregular polytopes. They are all formed by half the vertices of a hypercube (alternatingly truncated).
This one is called a demipenteract. It has 16 vertices, with 10 16-cells, and 16 5-cells.
The semiregular demipenteract can also be used to create 7 truncated forms. There are up to 3 types of hypercells, truncations of the 16-cell, truncations of the 5-cell, and truncations of the tetrahedral hyperprism.
Prismatic forms
There are 3 categorical uniform prismatic forms:
- {} x {p,q,r} - uniform polychoron prisms (Each uniform polychoron forms one uniform prism)
- {} x {3,3,3} - 9 forms
- {} x {3,3,4} - 15 forms (Three shared with {}x{3,4,3} family)
- {} x {3,4,3} - 10 forms
- {} x {3,3,5} - 15 forms
- Grand antiprism prism
- {p} x {q,r} - Regular polygon - uniform polyhedron duoprisms
- {p} x {3,3} - 5 forms for each (p>=3) (Three shared with {p}x{3,4} family)
- {p} x {3,4} - 7 forms for each (p>=3)
- {p} x {3,5} - 7 forms for each (p>=3)
- {} x {p} x {q} - Uniform duoprism prisms - 1 form for each p and q, (each >=3).
