In the geometry of hyperbolic 5-space, the 5-orthoplex honeycomb is one of five paracompact regular space-filling tessellations (or honeycombs).
It is paracompact because it has infinite vertex figures, with all vertices as ideal points at infinity.
With Schläfli symbol {3,3,3,4,3}, it has three 5-orthoplexes around each cell.
It is dual to the 24-cell honeycomb honeycomb.
Its vertex figure is the 16-cell honeycomb, {3,3,4,3}.
