In
eight-dimensional Euclidean geometry, the cyclotruncated 8-simplex honeycomb is a space-filling
tessellation (or
honeycomb). The tessellation fills space by
8-simplex,
truncated 8-simplex
In eight-dimensional geometry, a truncated 8-simplex is a convex uniform 8-polytope, being a truncation of the regular 8-simplex.
There are four unique degrees of truncation. Vertices of the truncation 8-simplex are located as pairs on the edge of ...

Structure
It can be constructed by nine sets of parallel
hyperplane
In geometry, a hyperplane is a subspace whose dimension is one less than that of its ''ambient space''. For example, if a space is 3-dimensional then its hyperplanes are the 2-dimensional planes, while if the space is 2-dimensional, its hyper ...
