English

A 3-dimensional Stasheff polytope

Noun

polytope ‎(plural polytopes)

1. (geometry) 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, ...".

     As is well known, the theory of linear inequalities is closely related to the study of convex polytopes.

     This polytope is mapped into a Cartesian force polytope (resp. torque polytope) in the Cartesian space. Such a polytope represents the exact force (resp. torque) that can be produced on the vehicle main body.

   • 2006, Rekha R. Thomas, Lectures in Geometric Combinatorics, page 27,

     Verify the Hirsch conjecture for the 3-cube, 4-cube and any other polytope that takes your fancy.

     The Steinitz theorem is a very satisfactory understanding of the graphs of three-dimensional polytopes.
