U+2279 "≹" Neither Greater-than nor Less-Than Unicode Character
Unicode Version 17.0
≹
U+2279 "≹" Neither Greater-than nor Less-Than is a mathematical symbol used to explicitly denote that two values are not comparable under the standard ordering of the real numbers, meaning the first is neither greater than nor less than the second. It serves as the logical negation of the relation "less than or greater than," effectively representing incomparability or the absence of an order relationship. This character is part of the Mathematical Operators block in Unicode and is commonly used in set theory, logic, and contexts involving partial orders or non-linear numeric systems where such a statement of non-comparison is required.
