WebBefore looking at sphere packings in 3D, we look at simpler examples of circle packings in 2D. 4.7.1. Packing density in 2D. We look at two lattice circle packings in 2D. They are called lattice packings because the centers of the circles are on a lattice. Consider the following question: Which of the following two 2D lattice packings

WebLattices are far more algebraically constrained, and it is widely believed that they do not achieve the optimal density in most dimen-sions. (For example, see [5, p. 140] for an example in R10 of a periodic packing that is denser than any known lattice.) By contrast, periodic packings at least come arbitrarily close to the optimal sphere ... dealerships that work with low creditWebSPHERE PACKINGS, LATTICES AND GROUPS Material for Third Edition J. H.
