WebA relation can be both symmetric and antisymmetric (in this case, it must be coreflexive), and there are relations which are neither symmetric nor antisymmetric (for example, the "preys on" relation on biological species). Antisymmetry is different from asymmetry: a relation is asymmetric if and only if it is antisymmetric and irreflexive.

WebExample 6.2.5. The relation T on R ∗ is defined as aTb ⇔ a b ∈ Q. Since a a = 1 ∈ Q, the relation T is reflexive. The relation T is symmetric, because if a b can be written as m n for some nonzero integers m and n, then so is its reciprocal b a, because b a = n m. If a b, b c ∈ Q, then a b = m n and b c = p q for some nonzero integers ...
