U+2AED "⫭" Reversed Double Stroke Not Sign Unicode Character
Unicode Version 17.0
⫭
U+2AED "⫭" Reversed Double Stroke Not Sign is a mathematical symbol used primarily in formal logic and set theory to denote negation, specifically a style of the logical "not" operator that features a double vertical stroke resembling a reversed or mirrored "not" sign. It belongs to the Supplemental Mathematical Operators block and is designed for contexts where a distinct visual variant of the negation symbol is needed, such as in advanced notation for binary relations or algebraic structures. Its appearance, with two parallel vertical lines, helps differentiate it from similar single-stroke negation symbols, thereby reducing ambiguity in complex mathematical expressions.
