On the set A = {a, b, c, d, e, f, g, h} is given by the relation R = {(a; b), (a; c), (a; d), (a; e), (b; f), (c; f), (d; g),
(e; g), (f; h), (g; h)}. Draw a Hasse Diagram for a partially ordered set (A, E), where C is the transitive-
reflexive closure of the relation R.
Answer (and justify) the following questions:
Is the (A, E) union set?
If so, is it an (a) distributive association, (b) bounded, (c) complementary, (d) a Boolean?
I know, how it works for number, so I can easily determine the infimum and supremum. But how can I
know it with letters?
I can't even move with this homework assignment, so please be more specific in explanation, so I can
----------
better understand the topic.
Thank
you a lot! And also, have a nice day.
