U+2284 "⊄" Not A Subset Of Unicode Character

U+2284 "⊄" Not A Subset Of is a mathematical symbol that represents the negation of the subset relation, indicating that one set is not completely contained within another set. It is formed by drawing a diagonal slash through the standard subset symbol "⊂", and it is commonly used in set theory, logic, and discrete mathematics to express that not every element of the first set belongs to the second set. This character belongs to the Mathematical Operators block in the Unicode standard, allowing for precise and computer-readable representation of this fundamental concept in formal mathematical writing.
