The ≸ symbol, officially known as "Neither Less Than Nor Greater Than," is a mathematical operator used to indicate that two values cannot be compared using standard inequalities. While this implies the values are equal on a standard number line, it takes on a special meaning in partially ordered sets to show that two elements are completely incomparable. You will mostly spot this niche symbol in advanced logic, set theory textbooks, and academic papers rather than everyday digital text.
