U+2AD4 "⫔" Superset Above Subset Unicode Character
Unicode Version 17.0
⫔
U+2AD4 "⫔" Superset Above Subset is a mathematical symbol used in set theory and logic to denote a specific relationship between two sets, indicating that one set is a superset positioned above a subset, essentially combining the concepts of a superset and a subset in a single glyph. It represents a relation where the larger set (superset) is conceptually placed above the smaller set (subset), often employed in formal notation to express containment or hierarchical structuring of sets within a given context. This character is part of the Supplemental Mathematical Operators block and is distinct from more common set symbols like ⊂ or ⊃, offering a precise way to convey a dual relationship without needing separate operators.
