Geometry
- The symmetry group of the tiling is 2*22 (cmm).
- All the internal angles of the constituent polygons are a multiple of 30°.
- Contains one regular two-pointed star polygon with vertex angle of 60°.
- There are one non-regular reflective pairs and no tiles with no mirror image.
- The tiling does not satisfy the two-colour condition.
- The tiling is edge-to-edge.
- The tiling satisfies the two-polygon condition.
- As drawn, contains about 99 polygons.
