U+22C3 "⋃" N-Ary Union Unicode Character

U+22C3 "⋃" N-Ary Union is a mathematical symbol that represents the union of a collection of sets, typically used in notation where the index set is finite or countably infinite. It functions as a large operator, analogous to the summation symbol Σ, allowing for the concise expression of a union over multiple sets, such as ⋃_{i=1}^{n} A_i. This character is distinct from the binary union operator ∪, which denotes the union of only two sets, and it is commonly employed in set theory, logic, and various branches of mathematics to indicate the set of all elements that belong to at least one of the specified member sets.
