Colour symmetry of 25 colours in quasiperiodic patterns
Résumé
Coloured periodic and quasiperiodic patterns with 25 colours and colour-symmetry were described for four-fold, six-fold, eight-fold, ten-fold, and twelve-fold symmetries. Eight-fold, twelve-fold and some four-fold patterns are related to coincidence site lattices (CSL). The procedures of delineation of coloured patterns with 25 colours must consider the property of a square number. Procedures for ten-fold patterns need special considerations and allow the description of superstructures.
