About the n-ary union symbol
N-Ary Union is a large, stylized capital U shape used in set theory and mathematics. It denotes the union of a collection of sets, producing a single set containing every element from any of the component sets.
This symbol is the operator counterpart to the binary union sign (∪), functioning as a summation-like notation over an indexed family of sets. It appears in textbooks, research papers, and formal logic contexts wherever generalized union operations are written.
