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.
