Could someone please tell me if the operator-set combination, where the operator is commutative but NOT associative, has any special name. For example, (fixed font makes this look correct) ... . | 0 | 1 | 2 | 3 | ------------------- 0 | 0 3 2 1 1 | 3 1 0 2 2 | 2 0 1 3 3 | 1 2 3 0 If it does, I'd very much like to know what it is. Cheers, Mark Diamond
