(definition)
Definition: A binary relation R for which a R a for all a.
See also symmetric, transitive, irreflexive.
Note: The relation "equals" is reflexive since everything is equal to itself. However the relation "less than" is not reflexive. The relation "likes" is not reflexive either since some people do not like themselves.
