Date: 11 Sep 1981 0917-PDT From: ISAACS at SRI-KL Subject: half query answer To: cube-lovers at MIT-MC First of all, I was inaccurate about the "Dinman" style "cube" - it doesn't only eliminate twisting, but also some positioning (ie, after the top and middle are solved, the bottom is automatically solved). Perhaps by the judicious adding of numbers to the facies, the pure position cube can be made. Also, the answer to the edge-only subgroup is easy - just remove all the labels from the corners, so they are all identically monochromatic. Is there a more elegant solution? --- Stan -------
