U+2A4A "⩊" Union Beside and Joined with Union Unicode Character

U+2A4A "⩊" Union Beside and Joined with Union is a mathematical symbol belonging to the Supplemental Mathematical Operators block, designed to represent a specialized set operation in which two union symbols are placed side by side and connected by a small horizontal line, indicating a combined or adjacent union of sets. It is typically used in advanced mathematical notation, such as set theory or lattice theory, to denote a union operation that applies simultaneously to two distinct collections or to express a structural relationship between unions in a compact, standardized form. Unlike common operators like ∪, this character provides a precise typographical representation for complex logical or algebraic expressions where proximity and connection between unions carry specific meaning.
