Truncated 6-cubes

• Truncated hexeract (Acronym: tox) (Jonathan Bowers)[1]

The truncated 6-cube may be constructed by truncating the vertices of the 6-cube at ${\displaystyle 1/({\sqrt {2}}+2)}$ of the edge length. A regular 5-simplex replaces each original vertex.

The Cartesian coordinates of the vertices of a truncated 6-cube having edge length 2 are the permutations of:

${\displaystyle \left(\pm 1,\ \pm (1+{\sqrt {2}}),\ \pm (1+{\sqrt {2}}),\ \pm (1+{\sqrt {2}}),\ \pm (1+{\sqrt {2}}),\ \pm (1+{\sqrt {2}})\right)}$

The truncated 6-cube, is fifth in a sequence of truncated hypercubes:

• Bitruncated hexeract (Acronym: botox) (Jonathan Bowers)[2]

The Cartesian coordinates of the vertices of a bitruncated 6-cube having edge length 2 are the permutations of:

${\displaystyle \left(0,\ \pm 1,\ \pm 2,\ \pm 2,\ \pm 2,\ \pm 2\right)}$

The bitruncated 6-cube is fourth in a sequence of bitruncated hypercubes:

• Tritruncated hexeract (Acronym: xog) (Jonathan Bowers)[3]

The Cartesian coordinates of the vertices of a tritruncated 6-cube having edge length 2 are the permutations of:

${\displaystyle \left(0,\ 0,\ \pm 1,\ \pm 2,\ \pm 2,\ \pm 2\right)}$
