Feb 2, 2011 at 21:04 comment added Joseph O'Rourke This is not an argument, but as you probably know, there are point configurations in the plane that cannot be realized with rational coordinates, as well as polyhedra whose combinatorial type cannot be realized with rational coordinates. It is at least conceivable that the Kemnitz/Harborth conjecture is false.
