U+2262 "≢" Not Identical To Unicode Character

U+2262 "≢" Not Identical To is a mathematical symbol used to express that two objects or values are not exactly the same in every respect, serving as the negation of the identity sign (≡). It is often employed in fields such as logic, number theory, and abstract algebra to indicate that two expressions are not equivalent under all circumstances, for example when demonstrating that two modulo congruences do not hold. The symbol resembles an equals sign with a third horizontal bar, all crossed by a diagonal slash, making it visually distinct from the similar but unrelated "not equal to" sign (≠).
