D13 Sphere

This is a Truncated Sphere D13. It has a 4-fold symmetry.

This die is inspired by the repulsion force polyhedra. But in this case, the underlying polyhedron (not rounded) does not exactly look like the shape that can be obtained through this technique with 13 points repulsing each others.
Instead, I calculated the positions of those points to have a maximal radius for the circles resulting from the intersection of this underlying polyhedron with a sphere. The result is a truncated sphere with 13 circular faces of same radius.

See this thread for more informations.

Thanks: I am happy to have found it because 13 is not a number easy to split (not only it is a prime, but also it cannot be writen as 3n+2 like 11 or 17). I will try to make a D19 with the same technique.
