... So pace Fuller and Coxeter, 6 spokes are both necessary and sufficient! The discrepancy between this result and Fuller's / Edmondson's 12 makes one wonder whether we're all discussing the same problem ...
There is a minor difficulty with the model above, in that it assumes two spokes may attach to the same point of the hub; however, I doubt this would invalidate the result. Maybe somebody out there could run up a hardware implementation, just to check? Or we could track down a wheel-builder --- all the ones I used to know are alas long gone ...
The 8 spoke arrangement suggested earlier has been verified experimentally: http://bobwb.tripod.com/synergetics/photos/bikerim.html WFL
