Diamond gets much of its strength from molecular/atomic binding forces. It is also tetrahedral. Speaking of diamond's strength purely from its geometry misses...
I agree, Adrian. The 'octane' has a lower apex than the reg.tet., thus the legs (edges) coming down from it to the base apices are at a shallower angle, hence ...
