Abstract
A two-dimensional quasiperiodic structure, based on tiles of three different shapes, has been generated using a modified strip-projection method. This structure belongs to the 4mm point symmetry group and can be viewed as an ordered derivative of fcc. The constituent tiles have been identified to be unimolecular subunit cells of three well known ordered structures of the fcc 1(1/20 family. The concept of a ‘‘rational modification of a truly quasiperiodic structure’’ is introduced.Keywords
