Axiom:Ordering Axioms/Formulation 2

Definition
Let $S$ be a set.

Let $\RR \subseteq S \times S$ be a relation on $S$.

$\RR$ satisfies the ordering axioms on $S$ $\RR$ satisifes the axioms:

where:
 * $\circ$ denotes relation composition
 * $\RR^{-1}$ denotes the inverse of $\RR$
 * $\Delta_S$ denotes the diagonal relation on $S$.
