U+2A47 "⩇" Intersection Above Union Unicode Character
Unicode Version 17.0
⩇
U+2A47 "⩇" Intersection Above Union is a mathematical operator from the Supplemental Mathematical Operators block, designed for use in advanced set theory and lattice algebra notation. It visually combines an intersection symbol placed directly above a union symbol, indicating a specific ordered operation where the intersection is applied before the union in a nested or composite expression. This character helps clarify complex formulas by providing a single glyph that represents a two step logical or algebraic combination, often appearing in academic texts or in work dealing with families of sets or distributive structures.
