- Source: Cubical bipyramid
In 4-dimensional geometry, the cubical bipyramid is the direct sum of a cube and a segment, {4,3} + { }. Each face of a central cube is attached with two square pyramids, creating 12 square pyramidal cells, 30 triangular faces, 28 edges, and 10 vertices. A cubical bipyramid can be seen as two cubic pyramids augmented together at their base.
It is the dual of a octahedral prism.
Being convex and regular-faced, it is a CRF polytope.
Coordinates
It is a Hanner polytope with coordinates:
[2] (0, 0, 0; ±1)
[8] (±1, ±1, ±1; 0)
