I found some info (pictures) about this at:

 <http://www.rickleephoto.com/mosaicfresnel.htm>
 <http://www.met.rdg.ac.uk/~swrgrgry/buckyball/buckyball.html>

(The last page claims to show a shere with 630 hexagons. I can't get
that number with your formula. n=4 gives 470 hexagons and n=5 gives 740
hexagons.)
