curprev 21:4721:47, 18 September 2024 77.7.18.144 talk 9,423 bytes −2 From my understanding when we have a 2-tuple, which can be seen as an ordered family indexed by the set 2 = {1,2} each element of the tuple is only indexed by one element of the index set 2. This is the case because the implied rule (function) that assigns an index to a family element is that the family element for a index i is the ith element in the tuple. undo
