Date: 15 Sep 1980 1842-PDT From: Alan R. Katz Subject: number of reachable states To: cube-lovers at MIT-MC I have seen the number 4.3 * 10^19 for the number of reachable states for the cube, can anyone tell me how you calculate it? This may have been answered before in this list, but I couldn't find it. Also, someone mentioned that one can make a checkerboard pattern from the Pons Asinorum by trebly rotating the centers by a simple transformation. Can anyone tell me this transformation? (again I may have missed reading it) Reply to either me or the list. Alan -------
