%I A084826 #13 Oct 17 2015 10:39:48 %S A084826 2,3,4,6,7,8,31,32,48,60,61,62,63 %N A084826 Best packing of m>1 equal spheres in a cube setting a new density record. %C A084826 The terms >=31 are only conjectures found by numerical experimentation. In the table given at the Pfoertner link, the densities are given relative to the density of the cubic lattice packing (Pi/6). The first known arrangement with higher density than that of the cubic lattice packing was found for m=31 spheres. In the region 8<m<27 increasing packing densities occur for m=9,13,14. m=14 comes very close (0.994949) to the cubic lattice packing density. %D A084826 See under A084824. %H A084826 Dave Boll, <a href="http://web.archive.org/web/20140228175551/http://home.comcast.net/~davejanelle/packing.html">Packing spheres in cubes</a> %H A084826 Hugo Pfoertner, <a href="http://www.randomwalk.de/sequences/a084824.txt">Best packing of equal spheres in a cube.
