The ⋬ (Not Normal Subgroup Of Or Equal To) symbol is a mathematical operator used primarily in abstract algebra. It combines a left-pointing triangle, an underline, and a forward slash to indicate that a given mathematical group is neither a normal subgroup of nor equal to another group. While highly specific to advanced mathematics, it occasionally appears in digital notes or technical documents discussing group theory.

In Programming
In mathematical typesetting languages like LaTeX, this symbol is generated using the command \ntrianglelefteq. It is strictly used for formatting abstract algebra equations and does not function as a logical operator in standard programming languages.
