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.
Zero dimension
One-dimensional regular polytope
There is only one polytope in 1 dimension, whose boundaries are the two endpoints of a line segment, represented by the empty Schläfli symbol {}.
