A relation R on a set A is defined to be irreflexive if, and only if, for every x ∈ A, x R x; asymmetric if, and only if, for every x, y ∈ A if x R y then y R x; intransitive if, and only if, for every x, y, z ∈ A, if x R y and y R z then x R z. Let A = {0, 1, 2, 3}, and define a relation R4 on A as follows. R4 = (1, 2), (2, 1), (1, 3), (3, 1) Is R4 irreflexive, asymmetric, intransitive, or none of these? R4 is irreflexive.R4 is asymmetric.R4 is intransitive.R4 is neither irreflexive, asymmetric, nor intransitive.
