Index Entry
Two pairs of seven-ball, triangular sets of closest packed spheres precess to associate as the cube. . . . This cube consists of 14 spheres whose number corresponds to the w 14 tetrahedral facets, the 14 faces of the vector equilibrium, and the 14 faces of Lord Kelvin’s tetrakaidecahedron, the all-space-filling, 14-faceted symmetrical polyhedron of eight hexagons and six squares. The cube shown is the minimum cube which may be stably produced by closest packed spheres. Eight spheres will not close pack as a cube and are utterly unstable.
