WebJun 26, 2024 · Jun 26, 2024 at 22:20 Usually, irreflexive means exactly that “for all x ∈ A, ( x, x) ∉ R ”, so that relation is not irreflexive. By the way, “irreflexive and transitive” implies “antisymmetric”: if (, y) ∈ R and ( y,) ∈, then ( x) ∈ R by transitivity, contradicting irreflexivity.

WebRepresentation of Relations using Graph. A relation can be represented using a directed graph. The number of vertices in the graph is equal to the number of elements in the set from which the relation has been defined. For each ordered pair (x, y) in the relation R, there will be a directed edge from the vertex ‘x’ to vertex ‘y’.
