What is the difference between polytope and polyhedron?

polytope | polyhedron |

Polyhedron is a hypernym of polytope.

Polyhedron is a hyponym of polytope.



In geometry terms the difference between polytope and polyhedron

is that polytope is a finite region of n-dimensional space bounded by hyperplanes; the geometrical entity represented by the general term of the infinite sequence "point, line, polygon, polyhedron, ..." while polyhedron is a solid figure with many flat faces and straight edges.
