Geometry
- The tiling has no symmetry group and hence is not a repeat pattern.
- All the internal angles of the constituent polygons are a multiple of 18°.
- There are one non-regular reflective pairs and no tiles with no mirror image.
- The tiling is edge-to-edge.
- As drawn, contains about 240 polygons.
