    P.S. Hopefully this is last known platonic primitive based on interpolation of icosa or dodeca hedrons... Truncated icosa and dodeca hedrons are also with equal edges and points lie also on sphere, but their side polygons are more complex than triangle and 5 sided-polygon, so it isn't advicable to consider them in this process... And snub dodecahedron is very complicated even to draw like 3D SOLID as some vertexes can't be exactly computed with CAD... (look into my videos on youtube and you'll see how complex snub dodecahedron is so it's also skipped from this process)...

    Regards, M.R.

    Registered forum members do not see this ad.

    Routines updated - removed duplicated faces (there were 3 downloads till now) - no need to overkill after execution...
