Rather than confining the term "polyhedron" to describe a three-dimensional polytope, it has been adopted to describe various related but distinct kinds of structure. A polyhedron has been defined as a set of points in real affine (or Euclidean) space of any dimensi…

WebbA simplex (plural simplices or simplexes) is the simplest possible non-degenerate polytope in each respective dimension. The n -dimensional simplex, or simply n-simplex, consists of n +1 vertices, with each n of them joined in the unique manner by a simplex of the lower dimension. Alternatively, one may construct an n -simplex as the pyramid of ...
