Stellated enneagonal tiling

The stellated enneagonal tiling or sent, also known as the enneagrammic tiling or order-9 enneagrammic tiling, is a regular star tiling of the hyperbolic plane. 9 enneagrams join at each vertex.

As the name suggests, it is a stellation of the enneagonal tiling. It is related to the spherical small stellated dodecahedron.
