U+2A46 "⩆" Union Above Intersection Unicode Character
Unicode Version 17.0
⩆
U+2A46 "⩆" Union Above Intersection is a mathematical symbol that belongs to the Supplemental Arrows-B and Operators block, specifically categorized under n-ary operators. It represents a composite set operation where the more familiar union symbol (∪) is placed directly above the intersection symbol (∩), typically used in advanced set theory or lattice theory to denote a combined operation or a specific ordering of these binary set operations. This character is encoded for use in technical and mathematical typesetting, allowing precise representation in digital text where it might appear in formal proofs, algebraic logic, or definitions involving combined subset relationships.
