In order to correct a parity problem (where you have to swap only 2 pieces rather than 4) I do the following move: (in Arensburger notation:) R,t3,b3,R,t1,b2,R,t2,b2,R,t6,R,b-2,t-2,R,b-2,t-1,R,b-3,t-3,R This scrambles the cube up a bit but makes it solvable using standard moves. There must be a better move than this! If anyone knows a better way to swap two pieces, let me know. -Noel
