2 | ∞ polygons | ∞ star polygons | 1 | 1 | 0 | 0 | ∞

There are no nonconvex Euclidean regular tessellations in any number of dimensions.

### Polytope elements

The elements of a polytope can be considered according to either their own dimensionality or how many dimensions "down" they are from the body.

* Vertex, a 0-dimensional element
* Edge, a 1-dimensional element
* Face, a 2-dimensional element
* Cell, a 3-dimensional element
* Hypercell or Teron, a 4-dimensional element
* Facet, an (n-1)-dimensional element
* Ridge, an (n-2)-dimensional element
* Peak, an (n-3)-dimensional element

For example, in a polyhedron (3-dimensional polytope), a face is a facet, an edge is a ridge, and a vertex is a peak.

* Vertex figure: not itself an element of a polytope, but a diagram showing how the elements meet.

### Tessellations

The classical convex polytopes may be considered tessellations, or tilings, of spherical space. Tessellations of euclidean and hyperbolic space may also be considered regular polytopes. Note that an 'n'-dimensional polytope actually tessellates a space of one dimension less. For example, the (three-dimensional) platonic solids tessellate the 'two'-dimensional 'surface' of the sphere.
