They can be derived with the help of a construction due to Nischke and Danzer. One of them has Bragg spectrum and therefore it is of interest in quasicrystal theory. An interpretation in terms of substitutional sequences is proposed.engjournal article10.1142/S0217984997000980restricted accessFísica nuclearFísica estadísticaFísica molecularFísica nuclear
