Polytope

In geometry, a polytope is the analog to a polygon or polyhedron in any number of dimensions. Alternatively, a polytope in n dimensions is a figure bounded by connected polytopes of dimension n-1. A polytope of 0 dimensions is a point, 1 dimension a line segment, 2 dimensions a polygon, 3 dimensions a polyhedron. Polytopes of 4 dimensions are sometimes called polychorons.
