Polychoron

A Polychor or Polychoron ( Mz Polychora ) is a 4 -dimensional polytope. Polychora bounded by polyhedra.

The simplest example is the Pentachoron, another well-known example is the tesseract, a generalization of the classical cube in four dimensions.

The two-dimensional analog of a Polychoron is a polygon, the three-dimensional polyhedron.
