U+27C9 "⟉" Superset Preceding Solidus Unicode Character

U+27C9 "⟉" Superset Preceding Solidus is a mathematical symbol included in the Miscellaneous Mathematical Symbols-A block, used primarily within notation for set theory and logical relations to denote a superset that is preceded by a solidus. Its design features a solidus, or forward slash, positioned before a large superset symbol, indicating a modified relationship such as "not a superset of" or a negation of superset inclusion. This character helps represent specific non-inclusion or reversed set relationships in formal mathematical texts, distinguishing it from the standard superset sign.
