A related question is "do these matches have a canonical form"? I do not know the answer to this question, but I can transform that 38 match competition you posted to this equally valid 38 match set: ABCD AEFG AHIJ AKLM ANOP AQRS ATUV BEKU BHQG BILW BNFV BRTJ BMXP EHCO EIRP EQVX ETDL EJMS HKDF HNTS HRUX HLVP IKTX INCU IFOS IGMV KNQW KROV KCJP NRGL NDJX QTCF QDMO QJLU RFMW TGOW CSXW DGSU -- Raul ---------------------------------------------------------------------- For information about J forums see http://www.jsoftware.com/forums.htm
