Order-3-7 hexagonal honeycomb with infinitely many hexagonal tilings existing around each vertex in an infinite-order triangular tiling vertex arrangement. It has a second construction as a uniform honeycomb, Schläfli symbol {6,(3,∞,3)}, Coxeter diagram, , with alternating types or colors of hexagonal tiling cells. Order-3-7 hexagonal honeycomb In the geometry of hyperbolic 3-space, the order-3-7 hexagonal honeycomb or (6,3,7 honeycomb) a regular space-filling tessellation (or honeycomb) with Schläfli symbol {6,3,7}. All vertices are ultra-ideal (existing beyond the ideal boundary) with seven hexagonal tilings existing around each edge and with an order-7 triangular tiling vertex figure. It a part of a sequence of regular polychora
