Uniform Antiprismatic Prism
In 4-dimensional geometry, a uniform antiprismatic prism is a uniform polychoron with two uniform antiprism cells in two parallel 3-space hyperplanes, connected by uniform prisms cells between pairs of faces.
A p-gonal antiprismatic prism has 4p triangle, 4p square and 4 p-gon faces. It has 10p edges, and 4p vertices.
The convex set includes:
| Name | Coxeter graph | Cells | Image |
|---|---|---|---|
| Triangular antiprismatic prism | 2 octahedra connected by 8 triangular prisms (same as the octahedral prism) | ||
| Square antiprismatic prism | 2 square antiprisms connected by 2 cubes and 8 triangular prisms | ||
| Pentagonal antiprismatic prism | 2 pentagonal antiprisms connected by 2 pentagonal prisms and 10 triangular prisms | ||
| Hexagonal antiprismatic prism | 2 hexagonal antiprisms connected by 2 hexagonal prisms and 12 triangular prisms | ||
| Heptagonal antiprismatic prism | 2 heptagonal antiprisms connected by 2 heptagonal prisms and 14 triangular prisms | ||
| Octagonal antiprismatic prism | 2 octagonal antiprisms connected by 2 octagonal prisms and 16 triangular prisms |
There are also nonconvex forms following the set of star antiprisms:
- Pentagrammic antiprismatic prism - - 2 pentagrammic antiprisms connected by 2 pentagrammic prisms and 10 triangular prisms
- Pentagrammic crossed antiprismatic prism - - 2 pentagrammic crossed antiprisms connected by 2 pentagrammic prisms and 10 triangular prisms

Famous quotes containing the words uniform and/or prism:
“When a uniform exercise of kindness to prisoners on our part has been returned by as uniform severity on the part of our enemies, you must excuse me for saying it is high time, by other lessons, to teach respect to the dictates of humanity; in such a case, retaliation becomes an act of benevolence.”
—Thomas Jefferson (1743–1826)
“Neither can I do anything to please critics belonging to the good old school of “projected biography,” who examine an author’s work, which they do not understand, through the prism of his life, which they do not know.”
—Vladimir Nabokov (1899–1977)
