|Type||Dual semiregular hyperbolic tiling|
|Symmetry group||[5,4], (*542)|
|Rotation group||[5,4]+, (542)|
|Dual polyhedron||truncated tetrapentagonal tiling|
In geometry, the 4-5 kisrhombille or order-4 bisected pentagonal tiling is a semiregular dual tiling of the hyperbolic plane. It is constructed by congruent right triangles with 4, 8, and 10 triangles meeting at each vertex.
The image shows a Poincaré disk model projection of the hyperbolic plane.
It is labeled V4.8.10 because each right triangle face has three types of vertices: one with 4 triangles, one with 8 triangles, and one with 10 triangles.
