Have you thought of using some other coding technique that might prove more easy to distinguish in any orientation? (Any idea what that might be?) -Dale [Moderator's note: I'm inordinately proud of my own invention, which I thought I mentioned years ago but can't find in the archives: Wire symbols glued to a destickered cube, polished to a high gloss. The symbols are blank opposite dot, square opposite circle, and plus opposite X. The supergroup is marked by a cutout at a corner of each face center and the adjacent cubies. I can solve it behind my back, but when I lent it to a blind computer scientist, he gave up. --Dan]
