Geometry
 
 
-  The symmetry group of the tiling is 22* (pmg).
-  All the internal angles of the constituent polygons are a multiple of 90°.
-  There are one non-regular reflective pairs and no tiles with no mirror image.
-  The tiling satisfies the interlace condition and has no finite interlace and  two infinite interlaces with straight cross-overs.
-  The tiling is edge-to-edge.
-  As drawn, contains about 30 polygons.
