In mathematics, especially in order theory, the greatest element of a subset $${\displaystyle S}$$ of a partially ordered set (poset) is an element of $${\displaystyle S}$$ that is greater than every other element of $${\displaystyle S}$$. The term least element is defined dually, that is, it is an element of See more Let $${\displaystyle (P,\leq )}$$ be a preordered set and let $${\displaystyle S\subseteq P.}$$ An element $${\displaystyle g\in P}$$ is said to be a greatest element of $${\displaystyle S}$$ if See more • A finite chain always has a greatest and a least element.
