<br><br></strong>This is a Truncated Sphere D13. It has a 4-fold symmetry.
<br><br>This die is inspired by the
<a href="http://members.ozemail.com.au/~llan/mpol.html">repulsion force polyhedra</a>. 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.
<br>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.
Basically, <br> is used to go to the line (enter), you can put as many of them as you want.
