| | BINARY RELATION - GoGoSearch.com |
 | | According to this view, the set of pairs {(1,2),(1,3),(2,7)} is a relation from any set that contains {1,2} to any set that contains {2,3,7}.Either approach is adequate for most uses, provided that one attends to the necessary changes in language, notation, and the definitions of concepts like restrictions, composition, inverse relation, and so on. |
 | | A relation which is reflexive, antisymmetric and transitive is called a partial order. |
 | | A partial order which is total is called a total order or a linear order or a chain. |
