Let us recall that the Cube is six-faced Symmetric Solid Object with exactly eight (8) [ nodal-points ] , and :
- the 8 [ nodal-points ] are all equi-distant from the [ centroid ] of Symmetric Solid Object .

This then permits us to put the 8 [ nodal-points ] onto the surface of a Sphere , so that :
- the 8 [ nodal-points ] are now all equi-distant from the [ center ] of the Sphere .
