6 degrees of freedom based on cartexsian three axi{ X, Y and Z }
pitch-2, yaw-2, and roll-2 left and right

However, to stabilize these six bilateral options i.e. to prevent torque/twist of a system, 12 restraints are needed. Here below is 12 restraints attached to 12 vertexes of and icosa{20}hedron.
The icosahedron is one of only three regular/symmetrical polyhedra possible of "
U "niverse.
However, there is another 12 vertexial polyhedron that is asymmetrical and not stable because it has 6 squares and squares have no 60 or 45 degree stability.
This 2nd, 12 vertexial polyhedron is known as the operating system of Universe, because its flexibality allows it to transform in to so many exotic shapes of space.

2 * 6 = 12
...X..........
3 * 4 = 12
12 is edges of stable octahedron and non-stable cube
2 and 3 are primes but only three defines a 2D area as a triangle.
4 can be 4 vertexes of tetrahedron{minimal structure of Universe }
6 is known as the smallest perfect number. My 6th birthday is the only one I remmeber from childhood, because my mother threw a suprise party for me.
The average of puberty for girls is 12. For boys 14 vertexes of the rhombic-dodecahedron has 12 faces.
