- | A '''regular''' [[polytope]] is a polytope whose [[hypercells]] are all [[congruent]].
| |
| | | |
- | In two dimensions, there are infinitely many regular polytopes, each one having a different number of sides.
| |
- |
| |
- | In three dimensions and above, there are five distinct sets of regular polytopes:
| |
- | *[[Simplex|Simplices]]
| |
- | *[[Hypercube]]s
| |
- | *[[Cross polytope]]s
| |
- | *[[Hyperdodecahedron|Hyperdodecahedra]]
| |
- | *[[Hypericosahedron|Hypericosahedra]]
| |
- |
| |
- | In four dimensions and no other dimension, there is also a sixth regular polytope, with several unique properties: the [[icositetrachoron]].
| |
- |
| |
- | Note that it does not make sense to speak of regularity in dimensions less than two.
| |
- |
| |
- | Since [[shape]]s can have curved hypercells, there are infinitely many regular ''shapes'' in any dimension, which is why we specify that regularity usually applies only to polytopes.
