Two Polygons, PP Class 101, [p6,c3,c1], IH Class 31.

• The symmetry group of the tiling is 632 (p6).
• All the internal angles of the constituent polygons are a multiple of 15°.
• Contains two equilateral triangles.
• There are no non-regular reflective pairs and one tile 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.
• The tiling satisfies the two-polygon condition.
• As drawn, contains about 62 polygons.
