U+2A48 "⩈" Union Above Bar Above Intersection Unicode Character
Unicode Version 17.0
⩈
U+2A48 "⩈" Union Above Bar Above Intersection is a mathematical operator used in advanced set theory and logic notation, specifically designed to represent a combined operation where a union symbol sits above a bar, which itself sits above an intersection symbol. This stacked arrangement denotes a structured relationship between union and intersection operations, often appearing in contexts involving lattices, order theory, or algebraic structures where hierarchical or sequential set operations need to be expressed in a single compact glyph. Its inclusion in the Unicode standard allows for precise typesetting in mathematical documents without requiring custom symbol creation.
