SUMMARY
The discussion focuses on constructing a directed graph (digraph) for two specific relations on the set {1, 2, 3, 4, 5}: (i) being a square of and (ii) being divisible without remainder. The first relation is defined as R = {(1,1), (2,4)}, indicating that 2 is the square of 4. The complete set of directed edges for the second relation is provided as {<1,2>, <1,3>, <1,4>, <1,5>, <2,3>, <2,4>, <2,5>, <3,4>, <3,5>, <4,5>}. A resource link is shared for further guidance on constructing the digraph.
