Subfacet

(This page is a grouping of multiple very low-effort articles worthy of deletions, but linked to heavily nonetheless. That is why this article itself may be very low quality too.)

An n-dimensional polytope is bounded by a number of (n − 1)-dimensional facets. They can also be called as "elements" of a polytope.

Subfacets include: vertices, edges, faces, cells, etc...

Vertex
A vertex is a zero-dimensional subfacet. Two or more vertices create an edge.

Edge
An edge is a one-dimensional subfacet. Two or more edges meet at a vertex. A face is made up of three or more edges.

Face
A face is a two-dimensional subfacet. Two or more faces meet at an edge.

Cell
A cell is a three-dimensional subfacet. Two or more cells meet at a face. A teron is made up of five or more cells.
