⨆
U+2A06 "⨆" N-Ary Square Union Operator is a mathematical symbol used primarily in set theory and algebra to denote the generalized union of a collection of sets, where the union is applied over an indexed family, similar to the standard big union symbol (⋃) but distinguished by its square shape. It typically appears in large operator notation, with limits or indices placed above and below the symbol in displayed formulas, indicating the union of sets ranging over a specified index set. This operator is part of the supplemental mathematical operators block and is included for specialized typesetting in academic and technical documents.
