Let R be the relation on the set {1, 2, 3, 4, 5} containing the ordered pairs (1, 3), (2, 4), (3, 1), (3, 5), (4, 3), (5, 1), (5, 2), and (5, 4). Find $$ \begin{array}{llll}{\text { a) } R^{2} .} & {\text { b) } R^{3}} & {\text { c) } R^{4}} \\ {\text { d) } R^{5} .} & {\text { e) } R^{6} .} & {\text { f) } R^{*}}\end{array} $$
