U+27C4 "⟄" Open Superset Unicode Character

U+27C4 "⟄" Open Superset is a mathematical symbol that visually resembles a standard superset sign (⊃) but with an open or hollow appearance on its left side, rather than being a fully closed or solid shape. It belongs to the Miscellaneous Mathematical Symbols-A block and is primarily used in set theory and logic to denote a relationship of superordination, often indicating that one set contains another, though its stylistic variation from the more common superset symbol can serve to highlight a specific formal property or contextual nuance, such as a partial or non-strict inclusion.
