Runcinated 5-orthoplexes

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

Contents

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

Alternate names

  • Runcinated pentacross
  • Small prismated triacontiditeron (Acronym: spat) (Jonathan Bowers)
  • Coordinates

    The vertices of the can be made in 5-space, as permutations and sign combinations of:

    (0,1,1,1,2)

    Alternate names

  • Runcitruncated pentacross
  • Prismatotruncated triacontiditeron (Acronym: pattit) (Jonathan Bowers)
  • Coordinates

    Cartesian coordinates for the vertices of a runcitruncated 5-orthoplex, centered at the origin, are all 80 vertices are sign (4) and coordinate (20) permutations of

    (±3,±2,±1,±1,0)

    Alternate names

  • Runcicantellated pentacross
  • Prismatorhombated triacontiditeron (Acronym: pirt) (Jonathan Bowers)
  • Coordinates

    The vertices of the runcicantellated 5-orthoplex can be made in 5-space, as permutations and sign combinations of:

    (0,1,2,2,3)

    Alternate names

  • Runcicantitruncated pentacross
  • Great prismated triacontiditeron (gippit) (Jonathan Bowers)
  • Coordinates

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

    ( 0 , 1 , 2 , 3 , 4 )

    Snub 5-demicube

    The snub 5-demicube defined as an alternation of the omnitruncated 5-demicube is not uniform, but it can be given Coxeter diagram or and symmetry [32,1,1]+ or [4,(3,3,3)+], and constructed from 32 snub 5-cells, 80 alternated 6-6 duoprisms, 40 icosahedral prisms, 10 snub 24-cells, and 960 irregular tetrahedrons filling the gaps at the deleted vertices.

    This polytope is one of 31 uniform 5-polytopes generated from the regular 5-cube or 5-orthoplex.
