In geometry, the Order 7 truncated heptagonal tiling, sometimes called the hyperbolic soccerball, is a semiregular tiling of the hyperbolic plane. There are two hexagons and one heptagon on each vertex, forming a pattern similar to a conventional soccer ball (truncated icosahedron) with heptagons in place of pentagons. It has Schläfli symbol of t1,2{7,3}.
Dual tiling
The dual tiling is called an order-3 heptakis heptagonal tiling, named for being constructable as a order-3 heptagonal tiling with every heptagon divided into 7 triangles by the center point.
