Dense order

In mathematics, a partial order or total order < on a set is said to be dense if, for all and in for which , there is a in such that . That is, for any two elements, one less than the other, there is another element between them. For total orders we can say this more simply as "for any two distinct elements, there is another element between them", since totality implies that two distinct elements are related by , but this is false in general for partial orders because distinct elements can be incomparable.
