U+2281 "⊁" Does Not Succeed Unicode Character
Unicode Version 17.0
⊁
U+2281 "⊁" Does Not Succeed is a mathematical symbol used to denote that one element does not succeed another, typically in a well ordered set or sequence, indicating the absence of a direct successor relationship. It is the negated form of the "succeeds" relation, often employed in mathematical logic, order theory, and discrete mathematics to express that a given item is not immediately followed by another in a defined ordering. This symbol belongs to the "Mathematical Operators" block of Unicode and is visually represented by a greater than sign with a slash through it, providing a clear, code independent way to convey negation in formal written mathematics.
