The pattern occurs as two ceramic dados in each of the southern alcoves in both east and west walls of the Salon de Comares. The colours alternate in the original.

• The symmetry group of the tiling is 4*2 (p4g).
• All the internal angles of the constituent polygons are a multiple of 45°.
• There is one non-regular reflective tile.
• The tiling satisfies the interlace condition and has one finite interlace and no infinite interlace with straight cross-overs.
• The tiling is edge-to-edge.
• As drawn, contains about 78 polygons.
