U+22DA "⋚" Less-than Equal to or Greater-Than Unicode Character

U+22DA "⋚" Less-than Equal to or Greater-Than is a mathematical symbol that combines three relational operators, indicating that one value is either less than or equal to another, or alternatively greater than that same value, without specifying which case holds true. It is frequently used in formal logic, set theory, and mathematical proofs to express a disjunctive relationship where two possibilities are both acceptable. This character belongs to the Miscellaneous Mathematical Symbols A block and is often paired with its reverse counterpart U+22DB, which denotes the opposite order of relations. Visually, it resembles a standard less-than sign with both an equal bar beneath it and an additional greater-than bar superimposed on its left side.
