How did we move from [ 64 ] to [ 60 ] ?
Some thoughts given here is that :
- May be we should be looking at the 2 tetrahedra within the Cube ,
- instead of the Cube itself ?
And if we do this , we would be focusing on :
- pairs of vectors intersecting at the angle of [ 109.47 degrees ] ;
because :
- 2 such { pairs of vectors } intersecting one-another at the angle of [ 109.47 degrees ]
- would give us 4 vectors in the formation of a tetrahedron ,
i.e. :
- 4 vectors intersecting one-another at the angle of [ 109.47 degrees ] .
