In mathematics, an asymmetric relation is a binary relation on a set where for all ,, ... An example of an asymmetric relation is the "less than" relation < ...
In mathematics, a relation denotes some kind of relationship between two objects in a set, which may or may not hold. [1] As an example, " is less than " is a relation on the set of natural numbers ; it holds, for instance, between the values 1 and 3 (denoted as 1 < 3 ), and likewise between 3 and 4 (denoted as 3 < 4 ), but not between the ...
In mathematics, asymmetry can arise in various ways. Examples include asymmetric relations, ... An asymmetric relation is a binary relation defined on a ...
In mathematics, a binary relation associates elements of one set called the domain with elements of another set called the codomain. [1] ... > is an asymmetric ...
A relation can be both symmetric and antisymmetric (in this case, it must be coreflexive), and there are relations which are neither symmetric nor antisymmetric (for example, the "preys on" relation on biological species). Antisymmetry is different from asymmetry: a relation is asymmetric if and only if it is antisymmetric and irreflexive.
Standard examples of posets arising in mathematics include: The real numbers, or in general any totally ordered set, ordered by the standard less-than-or-equal relation ≤, is a partial order. On the real numbers , the usual less than relation < is a strict partial order.

However, a relation can be neither symmetric nor asymmetric, which is the case for "is less than or equal to" and "preys on"). Symmetric and antisymmetric (where the only way a can be related to b and b be related to a is if a = b ) are actually independent of each other, as these examples show.
