or
AIC (5)R2C7=(5)R2C7-(5)R7C7=(5)R7C5-(5=9)R9C4-(9)R1C4=(9-5)R1C6=>-5R1C6=>stte (biunivocal correspondence with -9R1C4)
or
AIC (9)R7C5=(9)R9C4-(9=3)R1C4-(3)R3C5=(3-9)R5C5=>-9R5C5=>stte
or
AIC (5)R6C5=(5-9)R7C5=(9)R9C4-(9=3)R1C4-(3=4)R3C5-(4)R3C4=(4-5)R6C4=>-5R6C4=>stte (biunivocal correspondence with -4R6C5, -5R7C5, -9R7C2 , -6R7C7 and -6R9C2)
or
