Summary
| hexaoctagonal tiling | |
|---|---|
 Poincaré disk model of the hyperbolic plane | |
| Type | Hyperbolic uniform tiling |
| Vertex configuration | (6.8)2 |
| Schläfli symbol | r{8,6} or |
| Wythoff symbol | 2 | 8 6 |
| Coxeter diagram |    
|
| Symmetry group | [8,6], (*862) |
| Dual | Order-8-6 quasiregular rhombic tiling |
| Properties | Vertex-transitive edge-transitive |
In geometry, the hexaoctagonal tiling is a uniform tiling of the hyperbolic plane.
Constructions edit
There are four uniform constructions of this tiling, three of them as constructed by mirror removal from the [8,6] kaleidoscope. Removing the mirror between the order 2 and 4 points, [8,6,1+], gives [(8,8,3)], (*883). Removing the mirror between the order 2 and 8 points, [1+,8,6], gives [(4,6,6)], (*664). Removing two mirrors as [8,1+,6,1+], leaves remaining mirrors (*4343).

Symmetry edit
The dual tiling has face configuration V6.8.6.8, and represents the fundamental domains of a quadrilateral kaleidoscope, orbifold (*4343), shown here. Adding a 2-fold gyration point at the center of each rhombi defines a (2*43) orbifold. These are subsymmetries of [8,6].
