Bou Inania Madrasah

• Growth dynamic build of this pattern.
• Random dynamic build of this pattern.
• Structured dynamic build of this pattern.
• The symmetry group of the tiling is *442 (p4m).
• All the internal angles of the constituent polygons are a multiple of 45°.
• Contains four regular two-pointed star polygons with vertex angle of 45°.
• Contains five regular 8-pointed star polygons with vertex angle of 90°.
• There are 8 non-regular reflective tiles (including one kite and one dart) and one reflective pair.
• The tiling satisfies the interlace condition and has four finite interlaces and no infinite interlace with straight cross-overs.
• The tiling is edge-to-edge.
• As drawn, contains about 1823 polygons.
