ZILCH@MIT-MC 08/02/81 06:36:52 Re: 2edge-2corner swappers To: CUBE-LOVERS at MIT-MC I know of 4 different transforms that swap 2 edges and 2 corners. LD'BRDR'B2LBL2D (FD,RD),((DLF,DFR) R'DRD2R'L'DRD'LD2 (FD,LD),(FDL,FRD) FD2F'B'DFD'BD2F'D (FD,LD),(LFD,BDR) FLFL'UBLB'U2FUF (FD,DL),(DLF,DFR) I found the first 3 of these before I saw Singmaster and modified one of Singmaster's into the fourth one which he didn't even have recorded.
