WebJul 6, 2024 · There are a few combinations of properties that define particularly useful types of binary relations. The relation ≤ on the set N is reflexive, antisymmetric, and transitive. These properties define what is called a partial order: a partial order on a set A is a binary relation on A that is reflexive, antisymmetric, and transitive.
WebThis defines an ordered relation between the students and their heights. Therefore, we can say, ‘A set of ordered pairs is defined as a relation.’ This mapping depicts a relation from set A into set B. A relation from A to B is a subset of A x B. The ordered pairs are (1,c),(2,n),(5,a),(7,n).
