Mirza Akber, Leather Roll(1)

There is another version of this pattern which we think is incorrectly drawn, see Bibi-Khanym Mosque. Note that the V\&A drawing shows no evidence of an asymmetric tile.

• The symmetry group of the tiling is 2*22 (cmm).
• All the internal angles of the constituent polygons are a multiple of 36°.
• Contains one regular two-pointed star polygon with vertex angle of 72°.
• Contains two regular pentagons.
• Contains one regular 10-pointed star polygon with vertex angle of 108°.
• There are four non-regular reflective tiles (including one kite).
• 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 347 polygons.
