The Not Identical To symbol (≢) features a triple bar struck through with a diagonal slash, representing the mathematical concept of non-equivalence. In mathematics and formal logic, it is primarily used to indicate that two values, functions, or expressions are not identically equal, or not congruent in modular arithmetic. While rarely seen in casual texting or social media, it is essential in academic papers, technical documentation, and advanced math discussions to precisely define inequality.

In Programming
While most programming languages use operators like `!==` or `!=` for strict inequality in source code, ≢ frequently appears in theoretical computer science documentation and LaTeX formatting (using `\nequiv` or `\not\equiv`) to denote non-congruence.
