Hello Simon, Bartholomew's Projection comes pretty close, but it is not a true polyhedron. You've probably already hit this if you've been Googling but, an example is shown on this page: http://www.progonos.com/furuti/MapProj/Normal/ProjInt/ProjStar/projStar.html
Have you tried searching "tetrahedric" instead of "tetrahedral"?
