Great rhombitrihexagonal tiling

The great rhombitrihexagonal tiling, or grothat, also called the omnitruncated trihexagonal tiling, or othat, is one of the eleven convex uniform tilings of the Euclidean plane. 1 square, 1 hexagon, and 1 dodecagon join at each vertex of this tiling. As its name suggests, it is the omnitruncate of the V3 family of Euclidean tilings.
