If you are looking for the new files, you may have trouble because I
moved them into their own folder so the link in the previous posts is
no longer correct. However, you should have no problem finding them
if you check the Files link in the Platonic Solids discussion group.
The files do a thorough job analyzing the question of how many ways 8
cubes can be arranged and also pointing out some analogies with
molecular structures.
