J.J. Thomson (1904) asked: How do a small number of electrons arrange themselves on the surface of a unit sphere? Solutions have been proposed for cases where the number of electrons varies from 2 to 400 and beyond. However few solutions have been proved to be optimal.

Two types of polyhedra are useful for those working on the problem; the convex hull and its dual. A nice applet from Syracuse University shows virtual versions of these polyhedra.

(Run http://thomson.phy.syr.edu/thomsonapplet.php
Type n = 11 into the applet and press start - one can then alternate between the convex hull, "mesh", and its dual, "dual".)

It would be nice to print physical versions of these polyhedra and it was suggested to me that qhull - http://www.qhull.org/ - outputs these polyhedra in a simple format called OFF. I was able to write a program that coverts OFF format to openSCAD polyhedron commands.

Coordinates for possible solutions to the Thomson problem are available at The Cambridge C
