Question 37 (ii) Write the smallest equivalence relation on π. Given G = {g1, g2} We need to find smallest equivalence relation on π. Total possible pairs = {(g1, g1) , (g1, g2), (g2, g1), (g2, g2)} Reflexive means (a, a) should be in relation . So, (g1, g1) , (g2, g2) should be in a relation. Itβs important that both are elements of the relation Symmetric means if (a, b) is in relation, then (b, a) should be in relation . So, since (g1, g2) is in relation, (g2, g1) should also be in relation But this also is possible if we only have (g1, g1) and (g2, g2) in the relation Transitive means if (a, b) is in relation, & (b, c) is in relation, then (a, c) is in relation So, if (g1, g2) is in relation, & (g2, g1) is in relation, then (g1, g1) should be in relation But this also is possible if we only have (g1, g1) and (g2, g2) in the relation Thus, Smallest equivalence relation on G = {(g1, g1), (g2, g2)}
