U+2A49 "⩉" Intersection Above Bar Above Union Unicode Character

U+2A49 "⩉" Intersection Above Bar Above Union is a mathematical symbol used primarily in advanced set theory and logic, combining an intersection symbol above a horizontal bar, which in turn sits above a union symbol. This three‑part vertical arrangement indicates a specific operation or relation where the intersection and union are linked by that intermediate bar, often representing a form of generalized or iterated combination of sets. It belongs to the Supplemental Mathematical Operators block, making it available for precise notation in academic and technical documents that require specialized operators beyond the basic set theory symbols.
