In the geometry of hyperbolic 4-space, the order-4 120-cell honeycomb is one of five compact regular space-filling tessellations (or honeycombs). With Schläfli symbol {5,3,3,4}, it has four 120-cells around each face. Its dual is the order-5 tesseractic honeycomb, {4,3,3,5}.
Related honeycombs
It is related to the (order-3) 120-cell honeycomb, and order-5 120-cell honeycomb.
It is analogous to the order-4 dodecahedral honeycomb and order-4 pentagonal tiling.
