The following lemma shows that transitive sets play a prominent role in the set theory. They are omnipresent.

## Lemma: Any Set is Subset of Some Transitive Set - Its Transitive Hull

For every set $X$ there exists a transitive set $Y$, such that $X$ is a subset of $Y,$ formally $X\subseteq Y.$ This set is called the transitive hull of the set $X$.
