Nucleus:
In closest packing of spheres “the third layer of 92 spheres contains eight new potential nuclei which, however, do not become active nuclei until each has three more layers surrounding it-- three layers being unique to each nucleus. This tells us that the nuclear group with 92 spheres in its outer or third layer is the limit of unique, closest-packed assemblages of unit-wavelength and frequency, nuclear symmetry systems.”
