Pentellated 7-simplexes

In seven-dimensional geometry, a pentellated 7-simplex is a convex uniform 7-polytope with 5th order truncations (pentellation) of the regular 7-simplex.

Contents

There are 16 unique pentellations of the 7-simplex with permutations of truncations, cantellations, runcinations, and sterications.

Alternate names

  • Small terated octaexon (acronym: seto) (Jonathan Bowers)

    • Coordinates

    The vertices of the pentellated 7-simplex can be most simply positioned in 8-space as permutations of (0,0,1,1,1,1,1,2). This construction is based on facets of the pentellated 8-orthoplex.

    Alternate names

  • Teritruncated octaexon (acronym: teto) (Jonathan Bowers)

    • Coordinates

    The vertices of the pentitruncated 7-simplex can be most simply positioned in 8-space as permutations of (0,0,1,1,1,1,2,3). This construction is based on facets of the pentitruncated 8-orthoplex.

    Alternate names

  • Terirhombated octaexon (acronym: tero) (Jonathan Bowers)

    • Coordinates

    The vertices of the penticantellated 7-simplex can be most simply positioned in 8-space as permutations of (0,0,1,1,1,2,2,3). This construction is based on facets of the penticantellated 8-orthoplex.

    Alternate names

    Alternate names

  • Teriprismated octaexon (acronym: tepo) (Jonathan Bowers)

    • Coordinates

    The vertices of the pentiruncinated 7-simplex can be most simply positioned in 8-space as permutations of (0,0,1,1,2,2,2,3). This construction is based on facets of the pentiruncinated 8-orthoplex.
