Antiprism (disambiguation)

In three dimensions, an antiprism refers to a polygonal antiprism.

There are two contested definitions of the word antiprism in higher dimensions, along with one closely related concept.
 * Antiprism formed by lacing a polytope and its dual.
 * Alternated prism, which as the name indicates, is the alternation of a prism.
 * Alterprism formed by lacing two different orientations of the same polytope or even the same orientations, if a narrower than unit displacement (prism) exists additionally.
