	NationMaster - Encyclopedia: Singleton set
		Note that a set such as {{1,2,3}} is also a singleton: the only element is a set (which itself is however not a singleton).
		In axiomatic set theory, the existence of singletons is a consequence of the axiom of empty set and the axiom of pairing: the former yields the empty set {}, and the latter, applied to the pairing of {} and {}, yields the singleton {{}}.
		If A is any set and S is any singleton, then there exists precisely one function from A to S, the function sending every element of A to the one element of S.

	Math Notes - Relations
		Suppose that the element ‘a’ is a member of the universal set U. The set {a} is a singleton set. A singleton set represents a set such that all members of the set equal the same element. Thus, a singleton set may be defined as the following axiom.
		Some properties of singleton sets are not generally true for all sets. Theorem 3 is an equivalence expression for singleton sets, but only an implication if generalized to all sets.
		Theorem 3: {a} Í P Ú {a} Í Q º {a} Í (P È Q) A singleton set is a member of a set or the set’s complement. This property is not generally true of sets with two or more elements.

	[No title]
		The sets {a,b}, {a,c}, and {b,c} can be "fused" into the set {a,b,c} which is the smallest set which has all of them as "parts" (subsets), but the "fusion" of {a,b} and {a,c} gives the same result.
		My suggestion is that the role of the singleton construction is _semantic_; a singleton is a kind of _name_ for its element; a way of putting it which is perhaps better is that the singleton is a _token_ used to replace its element in the construction of sets.
		This formulation of the notion of "set" avoids (and perhaps illuminates) Russell's paradox: Let R be the "set of all sets which are not elements of themselves".

		In mathematics, a cofinite subset of a set X is a subset Y whose complement in X is a finite set.

		One approach is to filter out all of the duplicates in the first set before appending the two sets together.
		The definition also specifies that values contain one slot (also known as an instance variable or field).
		For example, we can define empty-set and singleton as follows: (define (empty-set ) (make elements: '())) (define (singleton ) (method ((i )) (make elements: (cons i '())))) To define member, we need some way to get at the list of elements in a set.
