For each of these relations on the set 21,22, 23,24], decide whether it is reflexive, whether it is symmetric, whether it is antisymmetric, and whether it is transitive.

(i) {(22, 22), (22, 23), (22, 24), (23, 22), (23, 23), (23, 24) }
(ii) {(21,21), (21,22), (22,21), (22,22), (23,23), (24,24)}

Determine whether the relation R1 and R2 on the set of all integer numbers is reflexive, symmetric, antisymmetric, and/or transitive, where (a, b) EZ if and only if
(i) R1 = {(a, b)la b).
(ii) R2 [(a, b)-a+bs 3].
