In the geometry of hyperbolic 4-space, the 120-cell honeycomb is one of five compact regular space-filling tessellations (or honeycombs).
With Schläfli symbol {5,3,3,3}, it has three 120-cells around each face.
Its dual is the order-5 5-cell honeycomb, {3,3,3,5}.
It is topologically similar to the finite 5-cube, {4,3,3,3}, and 5-simplex, {3,3,3,3}.
