Summary

Rhombitetraheptagonal tiling
Rhombitetraheptagonal tiling
Poincaré disk model of the hyperbolic plane
Type Hyperbolic uniform tiling
Vertex configuration 4.4.7.4
Schläfli symbol rr{7,4} or
Wythoff symbol 4 | 7 2
Coxeter diagram
Symmetry group [7,4], (*742)
Dual Deltoidal tetraheptagonal tiling
Properties Vertex-transitive

In geometry, the rhombitetraheptagonal tiling is a uniform tiling of the hyperbolic plane. It has Schläfli symbol of rr{4,7}. It can be seen as constructed as a rectified tetraheptagonal tiling, r{7,4}, as well as an expanded order-4 heptagonal tiling or expanded order-7 square tiling.

Dual tiling edit

The dual is called the deltoidal tetraheptagonal tiling with face configuration V.4.4.4.7.
