In geometry, the 1_{52} honeycomb is a uniform tessellation of 8-dimensional Euclidean space. It contains 1_{42} and 1_{51} facets, in a birectified 8-simplex vertex figure. It is the final figure in the 1_{k2} polytope family.
It is created by a Wythoff construction upon a set of 9 hyperplane mirrors in 8-dimensional space.
The facet information can be extracted from its Coxeter-Dynkin diagram.
Removing the node on the end of the 2-length branch leaves the 8-demicube, 1_{51}.
Removing the node on the end of the 5-length branch leaves the 1_{42}.
The vertex figure is determined by removing the ringed node and ringing the neighboring node. This makes the birectified 8-simplex, 0_{52}.
