• From the duplicate: > we can form the set $\{ \emptyset \}$ whose only member is $\emptyset$. Note that $\{ \emptyset \} \neq \emptyset$, because $\emptyset \in \{ \emptyset \}$ but $\underline{ \emptyset \notin \emptyset}$· – Dietrich Burde Jan 21 '17 at 17:27
$\emptyset$ is a set with no elements, $\{\emptyset\}$ is a set with one element.
