WebSep 1, 2024 · From Wikipedia - "Sphere packing in a sphere is a three-dimensional packing problem with the objective of packing a given number of equal spheres inside a unit sphere. It is the three-dimensional equivalent of the circle packing in a circle problem in two dimensions." For small numbers, the results are trivial: WebMay 17, 2024 · I subtracted $1$, the radius of the small spheres, because the centres of the surface spheres are located on a sphere of that radius, and that is where the packing takes place. Random circle packings have a density of about 82%, so packing an area of $4\pi (R-1)^2$ with circles of area $\pi 1^2=\pi$ we get:
