DESCRIPTION:Nanoparticles and colloids of various polyhedral shapes are sy
 nthesized and used as building blocks for self-assembly. It has been shown
  in simulations that a plethora of complex crystals and quasicrystals can 
 form entropically solely due to the anisotropic shape of the particles. At
  the limit of maximum density\, the densest packings\, as have been studie
 d in math for centuries\, becomes the relevant quantity. However\, a gener
 al understanding of how changes in shape affect packings and assemblies re
 mains largely unexplored. Here\, we study continuous families of polyhedra
  to demonstrate richness and complexity in behavior as a function of shape
 . We investigate connections between assemblies and densest packings\, dis
 cuss the possibility of predicting one from the other and outline general 
 guidelines for experiments.
