Abstract
We present an experiment of densification of a 2D horizontal assembly made of regular pentagons. The annealing leads to a dense crystalline arrangement with quasisixfold symmetry in spite of the geometrical cha racteristics of the grains and of the a priori short-range correlation length in the packing. This configuration yields the maximum average number of side to side contacts between the grains and probably the ma ximum packing fraction.
