A relation R on a set A is called Antisymmetric if and only if (a, b) € R and (b, a) € R, then a = b is called antisymmetric, i.e., the … WebLet T ( n) denote the number of transitive binary relations on an n -element set. So T (1) = 2 and T (2) = 13, for of the 16 possible relations on a 2-element set {a,b}, the only three which are not transitive are (i) { (a,b), (b,a)}, (ii) { (a,a), (a,b), (b,a)}, (iii) { (b,b), (a,b), (b,a)}.

WebCorrect option is A) The smallest equivalence relation is the identity relation R 1={(a,a),(b,b),(c,c)} Then two ordered pairs of two distinct elements can be added to give three more equivalence relations. R 2={(a,a),(b,b),(c,c),(a,b),(b,a)} Similarly R 3 and R 4 can be made by taking (b,c),(c,b) and (a,c),(c,a) respectively.
