WebBut then, for example, if a knows that prime numbers are divisible only by themselves and the number one, then a knows that 8683317618811886495518194401279999999 is prime (since this number is only divisible by itself and the number one). WebA transitive relation need not be reflexive. When it is, it is called a preorder. For example, on set X = {1,2,3}: R = { (1,1), (2,2), (3,3), (1,3), (3,2) } is reflexive, but not transitive, as the pair (1,2) is absent, R = { (1,1), (2,2), (3,3), (1,3) } is reflexive as well as transitive, so it …
