WebThe set T is defined as T = { (i, j) i, j ∈ Natural Numbers }, which means it contains all ordered pairs (i, j) where i and j are natural numbers. To show that T is countable, we need to show that there exists a one-to-one correspondence between T and the set of natural numbers. One possible way to do this is to use a diagonalization argument.
