Lemma: Comparing the Elements of Strictly Ordered Sets

In a strictly ordered set $(V,\prec)$, for all elements \(a,b\in V\) exactly one of the following cases holds:

  • Either $a \prec b$ ($a$ is smaller than $b$),
  • or $a \succ b$ ($a$ is greater than $b$).
  • else $a=b$ ($a$ equals $b$).

Because of these three possibilities, the strict order $”\prec”$ is sometimes also called a trichotomous order.
