Abstract

"In the two-dimensional space, the maximal packing density for identical circles is given by π/(2 √3) ≈ 0.9069 [2]. This density is reached on square and hexagonal periodic lattices. In 1611, Johannes Kepler conjectured that in the 3D space, both a face-centered cubic packing (fcc) and a hexagonal close packing (hcp) of congruent spheres give a density of π/(3 √2) ≈ 0.74048." These changes have no material impact on the conclusions of the paper. The authors would like to apologize for any inconvenience caused to the readers by these changes.
