U+2278 "≸" Neither Less-than nor Greater-Than Unicode Character
Unicode Version 17.0
≸
U+2278 "≸" Neither Less-than nor Greater-Than is a mathematical symbol used to denote that two values or quantities are not comparable under the standard less-than or greater-than relations, often implying they are incomparable or that the usual ordering does not apply. It consists of a less-than sign and a greater-than sign superimposed with a diagonal slash through both, functioning as a logical negation of the ordering relationship. This character is typically employed in advanced mathematics, set theory, or logic to express that one element is neither less than nor greater than another, possibly due to partial ordering or undefined comparisons.
