Another family of tilings associated to the zonotope formula_6 are the "zonotopal tilings" of formula_6. A collection of zonotopes is a zonotopal tiling of formula_6 if it a polyhedral complex with support formula_6, that is, if the union of all zonotopes in the collection is formula_6 and any two intersect in a common (possibly empty) face of each. Many of the images of zonohedra on this page can be viewed as zonotopal tilings of a 2-dimensional zonotope by simply considering them as planar objects (as opposed to planar representations of three dimensional objects). The Bohne-Dress Theorem states that there is a bijection between zonotopal tilings of the zonotope formula_6 and "single-element lifts" of the oriented matroid formula_21 associated to formula_6.
