What is the package factor for spheres in a spherical container ? We assume that the spheres are microscopic compared to the container. It does NOT equal Kepler’s conjecture which is valid for tetrahedral containers only !!

Package factors for:

tetrahedral container = pi/sqr.18=0,78048…

rectangular container = pi/sqr.20,25=0,69813…

spherical container = ???

Who can answer this question ?
