Runcinated 5-cubes

In five-dimensional geometry, a runcinated 5-cube is a convex uniform 5-polytope that is a runcination (a 3rd order truncation) of the regular 5-cube.

Contents

There are unique 8 degrees of runcinations of the 5-cube, along with permutations of truncations, and cantellations. Four are more simply constructed relative to the 5-orthoplex.

Alternate names

  • Small prismated penteract (Acronym: span) (Jonathan Bowers)
  • Coordinates

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

    ( ± 1 ,   ± 1 ,   ± 1 ,   ± ( 1 + 2 ) ,   ± ( 1 + 2 ) )

    Alternate names

  • Runcitruncated penteract
  • Prismatotruncated penteract (Acronym: pattin) (Jonathan Bowers)
  • Construction and coordinates

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

    ( ± 1 ,   ± ( 1 + 2 ) ,   ± ( 1 + 2 ) ,   ± ( 1 + 2 2 ) ,   ± ( 1 + 2 2 ) )

    Alternate names

  • Runcicantellated penteract
  • Prismatorhombated penteract (Acronym: prin) (Jonathan Bowers)
  • Coordinates

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

    ( ± 1 ,   ± 1 ,   ± ( 1 + 2 ) ,   ± ( 1 + 2 2 ) ,   ± ( 1 + 2 2 ) )

    Alternate names

  • Runcicantitruncated penteract
  • Biruncicantitruncated 16-cell / Biruncicantitruncated pentacross
  • great prismated penteract (gippin) (Jonathan Bowers)
  • Coordinates

    The Cartesian coordinates of the vertices of a runcicantitruncated 5-cube having an edge length of 2 are given by all permutations of coordinates and sign of:

    ( 1 ,   1 + 2 ,   1 + 2 2 ,   1 + 3 2 ,   1 + 3 2 )

    These polytopes are a part of a set of 31 uniform polytera generated from the regular 5-cube or 5-orthoplex.
