It a part of a sequence of regular polychora and honeycombs {p ,6,p }:
Order-6-6 hexagonal honeycomb
Order-5-6 hexagonal honeycomb
Type Regular honeycomb
Schläfli symbols {6,6,6} {6,(6,3,6)}
Coxeter diagrams =
Cells {6,6}
Faces {6}
Edge figure {6}
Vertex figure {6,6} {(6,3,6)}
Dual self-dual
Coxeter group [6,5,6] [6,((6,3,6))]
Properties Regular
In the geometry of hyperbolic 3-space , the order-6-6 hexagonal honeycomb (or 6,6,6 honeycomb ) is a regular space-filling tessellation (or honeycomb ) with Schläfli symbol {6,6,6}. It has six order-6 hexagonal tilings , {6,6}, around each edge. All vertices are ultra-ideal (existing beyond the ideal boundary) with infinitely many hexagonal tilings existing around each vertex in an order-6 hexagonal tiling vertex arrangement .
It has a second construction as a uniform honeycomb, Schläfli symbol {6,(6,3,6)}, Coxeter diagram, , with alternating types or colors of cells. In Coxeter notation the half symmetry is [6,6,6,1+ ] = [6,((6,3,6))].
