Truncated 8-orthoplexes

Alternate names • Truncated octacross (acronym: tek) (Jonthan Bowers) Construction There are two Coxeter groups associated with the truncated 8-orthoplex, one with the C8 or [4,3,3,3,3,3,3] Coxeter group, and a lower symmetry with the D8 or [35,1,1] Coxeter group. Coordinates Cartesian coordinates for the vertices of a truncated 8-orthoplex, centered at the origin, are all 224 vertices are sign (4) and coordinate (56) permutations of : (±2,±1,0,0,0,0,0,0) Images == Bitruncated 8-orthoplex ==

Alternate names • Bitruncated octacross (acronym: batek) (Jonthan Bowers) Coordinates Cartesian coordinates for the vertices of a bitruncated 8-orthoplex, centered at the origin, are all sign and coordinate permutations of : (±2,±2,±1,0,0,0,0,0) Images == Tritruncated 8-orthoplex ==
