Not if 1,2,3 are integers, or you accept meaningless definitions which are really not relations. Frankly, I wavered on acceptable subsets. I don't believe they apply for the integers, depending on the definition of "relation," for example {(1,1), (1,2)}, but that's a topic for another discussion. In any event, your post 2 set is not a possible relation for the integers.
