91Uniform polytope — A uniform polytope is a vertex transitive polytope made from uniform polytope facets. A uniform polytope must also have only regular polygon faces.Uniformity is a generalization of the older category semiregular, but also includes the regular… …
92Reduced cost — In linear programming, reduced cost, or opportunity cost, is the cost for increasing a variable by a small amount, i.e., the first derivative from a certain point on the polyhedron that constraints the problem. When the point is a vertex in the… …
93Dual polygon — In geometry, polygons are associated into pairs called duals, where the vertices of one correspond to the edges of the other. Contents 1 Properties 2 Kinds of duality 2.1 Rectification …
94Archimedean solid — In geometry an Archimedean solid is a highly symmetric, semi regular convex polyhedron composed of two or more types of regular polygons meeting in identical vertices. They are distinct from the Platonic solids, which are composed of only one… …
95Polychoron — In geometry, a four dimensional polytope is sometimes called a polychoron (plural: polychora), from the Greek root poly , meaning many , and choros meaning room or space .It is also called a 4 polytope or polyhedroid. The two dimensional analogue …

97Alternation (geometry) — In geometry, an alternation (also called partial truncation ) is an operation on a polyhedron or tiling that fully truncates alternate vertices. Only even sided polyhedra can be alternated, for example the zonohedra. Every 2n sided face becomes n …
