Abstract

In the present work we study the means to produced icosahedral and decahedral spiral structures based on the ideas of Mackay and Bernal. It is found that indeed it is possible to generate spirals with five-fold or ten fold symmetry axes which might be structural unit for Quasicrystals. These types of structures are already present in many biological systems
