PERFECT AND IMPERFECT ICOSAHEDRAL SOLIDS AND THE PROJECTION METHOD

Abstract
We consider extensions of the projection technique for describing icosahedral solids. The relationship between the projection method and the generalized dual method for describing quasiperiodic lattices is considered. Quasiperiodic lattices not fitting into the ordinary projection scheme are discussed. Experimental icosahedral solids, which are not perfect quasiperiodic structures, can nevertheless be described by a random projection procedure.
