U+2AD8 "⫘" Superset Beside and Joined by Dash with Subset Unicode Character
Unicode Version 17.0
U+2AD8 "⫘" Superset Beside and Joined by Dash with Subset is a mathematical symbol belonging to the Supplemental Mathematical Operators block, designed to denote a specific set-theoretic relationship. This symbol graphically combines a superset sign placed beside a subset sign, connected by a horizontal dash, to represent that one set is a superset of another while also being linked in a relational manner indicated by the dash. It is used in formal logic and set theory to express a nuanced relationship where one set contains the elements of another but is also directly tied to it through an additional structural or definitional connection. The character supports precise notation in advanced mathematics and computer science, particularly in contexts requiring clear differentiation from similar but simpler superset or subset operators.
