Geometry
 
 
-  The symmetry group of the tiling is *632 (p6m).
-  All the internal angles of the constituent polygons are a multiple of 30°.
-  Contains one regular 6-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 145 polygons.
