Abstract
This note contains a simple proof of the following theorem, which was (very nearly) stated by R. Buckminster Fuller (Marks, 1960, p. 35):
When congruent balls are arranged in cubic close-packing so as to fill a tetrahedron, square pyramid, octahedron, cuboctahedron, truncated tetrahedron or truncated octahedron, with n+1 balls along each edge, the total number of peripheral balls is \[bn2\, + \,2,\] \( b{{n}^{2}}{\mkern 1mu} + {\mkern 1mu} 2, \) where b = 2, 3, 4, 10, 14 or 30, respectively.
