That went down with the mob rather like Oleg McNoleg's lead snowshoes, so he invented some planetary laws instead, but the rd's remained out there. I last used my net at a school near you in about 1998 to teach the idea that crystals are made up of repeating structures, even weird ones, but I originally created it when I was playing with an idea for a sort of 3D version of GO, played on a finite field, the apices of a dodecahedron. Anyhow, it must be in the dungeon, sorry, store-room somewhere. It can be done, and I commend it to you as an exercise -- or ask for a copy to be scanned and sent.
