### Etymology[edit]

From German *Polytop*, equivalent to *poly-* (“many”) + *-tope* (“surface”). Coined by Hoppe in 1882 and introduced to English by Alicia Boole Stott.^{[1]}

### Noun[edit]

**polytope** (*plural* **polytopes**)

- (geometry) A finite region of
*n*-dimensional space bounded by hyperplanes (a geometric shape with flat sides, existing in any number of dimensions); the geometrical entity represented by the general term of the infinite sequence "point, line, polygon, polyhedron, ...".**1964**, Victor Klee,*On the Number of Vertices of a Convex Polytope*,*Canadian Journal of Mathematics*, Volume XVI, Number 4, page 701,- As is well known, the theory of linear inequalities is closely related to the study of convex
