WebIn mathematics, a relation on a set may, or may not, hold between two or more given set members; the number of elements involved is called the arity of the relation. For example, "is less than" is a binary relation on the set of natural numbers; it holds e.g. between 1 and 3 (denoted as 1<3) , and likewise between 3 and 4 (denoted as 3<4), but ...

Step 1/4. (a) To determine if the relation. r = f. on F is reflexive, symmetric, antisymmetric, and transitive, we need to check each property: Reflexivity: A relation is reflexive if for every element a in the set A, aRa holds.
