SUMMARY
The discussion focuses on defining a relation R on the set S = {1, 2, 5, 6} with at least four ordered pairs. The relation is established as (a, b) ∈ R if and only if the product a * b is even. This definition leads to the identification of valid pairs such as (2, 1), (2, 2), (2, 5), and (2, 6), as well as (6, 1), (6, 2), (6, 5), and (6, 6). The emphasis is on understanding the properties of even and odd products in the context of discrete mathematics.
