Definition:Strict Ordering/Notation

Definition
Symbols used to denote a general ordering relation are usually variants on $\prec$, $<$ and so on.

On, to denote a general ordering relation it is recommended to use $\prec$.

To denote the conventional ordering relation in the context of numbers, the symbol $<$ is to be used.

The symbol $\subset$ is universally reserved for the (proper) subset relation.


 * $a \prec b$

can be read as:
 * $a$ (strictly) precedes $b$.

Similarly:
 * $a \prec b$

can also be read as:
 * $b$ (strictly) succeeds $a$.

If, for two elements $a, b \in S$, it is not the case that $a \prec b$, then the symbols $a \nprec b$ and $b \nsucc a$ can be used.
