  • $\begingroup$ 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} $· $\endgroup$ – Dietrich Burde Jan 21 '17 at 17:27

No!

$\emptyset$ is a set with no elements, $\{\emptyset\}$ is a set with one element.
