"The examples use the poset consisting of the set of all subsets of a three-element set ordered by set inclusion (see Fig.1). • a is related to b when a ≤ b. This does not imply that b is also related to a, because the relation need not be symmetric. For example, is related to but not the reverse. " - How many least elements in a poset

Conversely, given an ordered set P with that property, deﬁne x∧y = g.l.b.(x,y) and x ∨y = l.u.b.(x,y). Then (P,∧,∨) is a lattice.
