Cantellated 5-cubes

In six-dimensional geometry, a cantellated 5-cube is a convex uniform 5-polytope, being a cantellation of the regular 5-cube.

There are 6 unique cantellation for the 5-cube, including truncations. Half of them are more easily constructed from the dual 5-orthoplex

Alternate names

  • Small rhombated penteract (Acronym: sirn) (Jonathan Bowers)

Coordinates

The Cartesian coordinates of the vertices of a cantellated 5-cube having edge length 2 are all permutations of:

Bicantellated 5-cube

In five-dimensional geometry, a bicantellated 5-cube is a uniform 5-polytope.

Alternate names

  • Bicantellated penteract, bicantellated 5-orthoplex, or bicantellated pentacross
  • Small birhombated penteractitriacontaditeron (Acronym: sibrant) (Jonathan Bowers)

Cantitruncated 5-cube

Alternate names
