• the set of months with 32 days. We call a set with no elements the null or empty set.

$\huge\sf\bold{\pink{Void \: set}}$

The empty set is the unique set having no elements; its size or cardinality (count of elements in a set) is zero. In that setting, it describes a set of measure zero; such a set is not necessarily empty. The empty set may also be called the void set.
