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

Polytope elements sunting

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

  • Puncak, sebuah elemen dimensi 0
  • Sisi, sebuah elemen dimensi 1
  • Wajah, sebuah elemen dimensi 2
  • Sel, sebuah elemen dimensi 3
  • Hipersel, sebuah elemen dimensi 4
  • Facet, sebuah (n-1)
  • Ridge, sebuah elemen dimensi (n-2)
  • Peak, sebuah elemen dimensi (n-3)

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.

Teselasi sunting

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.
