U+2285 "⊅" Not A Superset Of Unicode Character

U+2285 "⊅" Not A Superset Of is a mathematical symbol used in set theory to denote that one set is not a superset of another, meaning that the set on the left does not contain every element of the set on the right. It is the visual inverse of the superset symbol (⊃) with a negation slash through it, and in LaTeX it is typically rendered using the command otsupset. This operator is useful in formal logic, mathematics, and computer science for expressing inequality relationships between collections or classes, often appearing in proofs or statements involving containment.
