## Relations
-| Relation | Explanation | Example |
-| ---------------- | --------------------------------------------------------------------------------------------------------------------- | ----------------------- |
-| *transitive*
| "chain reaction", a information about $a$ in relation to $c$ can be inferred from the relations $a -> b$ and $b -> c$ | $a < b, b < c => a < c$ |
-| *reflexive* | every element is related to itself with the given relation | $a <= a, 5 = 5$ |
-| *anti-reflexive* | every element is *NOT* related to itself in the given relation | $a < a$ |
-| *symmetric* | the given relation work both ways | $a = b => b = a$ |
