6.2.22 BINARY RELATIONS

Condition: on the set \ (a = \ {a, b, c, d, e \} \) the ratio is set \ (p = \ {(a, a), (a, d), (a, e), (b, b), (b, c), (c, b), (c, c) \), \ (d, a), (d, d), (d, e), (e, a) (e) (e, a) (e) (e) d), (e, e) \} \). To portray it on the graph, on the column, matrix. Determine the properties of the relationship \ (p \). If \ (p \) equivalence, then find its equivalence classes. If \ (p \)-the ratio of order, then depict the Hasse chart, find the maximum and minimum, smallest and largest elements of the set \ (A \).
