I'm talking about the Tetrahedron with a friend just recently, 3 dimensional shape of 3 sides and 3 points.
This is regarded as a Sacred Solid, It's relation to the numbers 3, 33 and 333 are quiet evident.
This is a very hefty subject matter so I'll leave it to someone who is versed in the sacred solids.
