I know that the Hasse diagram is used to represent a finite partially ordered set, in the form of a drawing of its transitive reduction, but I have always been bad with graphs and drawing them. Can anyone help with these 2 Hasse diagram problems?

1) Draw the Hasse diagram for the poset (P(U), ⊆), where U = {1, 2, 3, 4}.

Exercise 7.3

6)For A = {a, b, c, d, e}, the Hasse diagram for the poset (A, R) is shown in Fig. 2.3.

Determine the relation matrix for R.
