The stellated heptagonal tiling or sheat, also known as the heptagrammic tiling or order-7 heptagrammic tiling, is a regular star tiling of the hyperbolic plane. 7 heptagrams join at each vertex.

As the name suggests, it is a stellation of the heptagonal tiling. It is related to the spherical small stellated dodecahedron, which can be obtained from a similar stellation of the regular dodecahedron.
