Imperfect Congruence: Tiling with Regular Polygons and Rhombs
Kevin Jardine Proceedings of Bridges 2013: Mathematics, Music, Art, Architecture, Culture (2013) Pages 439–442
Edge-to-edge plane tilings of regular polygons can include only
squares, triangles, hexagons, octagons, and dodecagons. The
possibilities become far larger, striking and beautiful if we add
rhombs to the prototile set.
