The structural diversity of the non fragmented structures was analysed using order parameters which were chosen as the number of 5 or 6 carbon rings and the asphericity constant $\\beta$. The most abundant and lowest energy population was found to correspond to a flakes population, constituted of isomers of variable shapes possessing a large number of 5 or 6-carbon rings.
