Grand antiprism
Videos
In geometry, the grand antiprism or pentagonal double antiprismoid is a uniform 4-polytope bounded by 320 cells: 20 pentagonal antiprisms, and 300 tetrahedra. It is an anomalous, non-Wythoffian unifor
100 tetrahedra in a 10×10 array forming the Clifford torus boundary in the 600-cell and grand antiprism.
Prism (geometry)

In geometry, a prism is a polyhedron comprising an n-sided polygon base, a second base which is a translated copy of the first, and n other faces, necessarily all parallelograms, joining corresponding
A {23}×{29} duoprism, showing edges in stereographic projection. The squares make a 23×29 grid flat torus.
