WebA set is thus determined by its elements. Let A and B be sets. We say that A and B are equal, if they consist of the same elements; that is, x ∈ A ⇐⇒ x ∈ B. The set with no elements is called the empty set and is denoted by ∅. For any object x, there is a set A whose only member is x. This set is denoted by {x} and called a singleton.

WebA singleton set is a set with exactly one element; such a set may also be called a unit set. [6] Any such set can be written as { x }, where x is the element. The set { x } and the element x … In particular, there is only one set with no elements at all. This set is called, naturally, the empty set , and is represented by the symbol \({\varnothing}\).
