Sultan Barsbay Funerary Complex, Cairo

• 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 2.5°.
• Contains one regular 8-pointed star polygon with vertex angle of 90°.
• Contains one regular 12-pointed star polygon with vertex angle of 65°.
• There are 6 non-regular reflective tiles (including 2 kites) and one reflective pair.
• The tiling satisfies the interlace condition and has no finite interlace and one infinite interlace with straight cross-overs.
• The tiling is edge-to-edge.
• As drawn, contains about 476 polygons.
