WebAn example of an irreflexive relation, which means that it does not relate any element to itself, is the "greater than" relation ([math]\displaystyle{ x \gt y }[/math]) on the real numbers.Not every relation which is not reflexive is irreflexive; it is possible to define relations where some elements are related to themselves but others are not (that is, … WebA quasi-order (also called a preorder ) is just a relation which is transitive and reflexive. This is a weak kind of ordering, but is quite common. For example, we might say a is "as well qualified" as b if a has all qualifications that b has. This relation is a quasi-order. A quasi-order is a partial order if it is also antisymmetric.
