Hexaoctagonal tiling

In geometry, the hexaoctagonal tiling is a uniform tiling of the hyperbolic plane.

Poincaré disk model of the hyperbolic plane
Type	Hyperbolic uniform tiling
Vertex configuration	(6.8)2
Schläfli symbol	r{8,6} or ${\displaystyle {\begin{Bmatrix}8\\6\end{Bmatrix}}}$
Wythoff symbol	2 | 8 6
Coxeter diagram
Symmetry group	[8,6], (*862)
Dual	Order-8-6 quasiregular rhombic tiling
Properties	Vertex-transitive edge-transitive

Constructions

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

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].
