Abstract Polytope

An abstract polytope is a partially ordered set, whose elements we call faces, satisfying the 4 axioms:

  1. It has a least face and a greatest face.
  2. All flags contain the same number of faces.
  3. It is strongly connected.
  4. Every 1-section is a line segment.

An n-polytope is a polytope of rank n.

Famous quotes containing the word abstract:

    When needs and means become abstract in quality, abstraction is also a character of the reciprocal relation of individuals to one another. This abstract character, universality, is the character of being recognized and is the moment which makes concrete, i.e. social, the isolated and abstract needs and their ways and means of satisfaction.
    Georg Wilhelm Friedrich Hegel (1770–1831)
