Great heptagonal tiling

The great heptagonal tiling or gheat, also known as the heptagrammic-order heptagonal tiling, is a regular star tiling of the hyperbolic plane. 7 heptagons join at each vertex in a heptagrammic arrangement.

It is a faceting of the order-7 triangular tiling, using the bases of its heptagonal pyramid caps as faces. It is related to the spherical great dodecahedron, which can be obtained from a similar faceting of the regular icosahedron.
