U+22EA "⋪" Not Normal Subgroup Of Unicode Character
Unicode Version 17.0
⋪
U+22EA "⋪" Not Normal Subgroup Of is a mathematical symbol used in group theory to indicate that a particular subgroup is not a normal subgroup of a larger group. It visually resembles a "⊲" (normal subgroup symbol) with a diagonal slash through it, functioning as a negation operator in algebraic notation. This character allows mathematicians to concisely express the failure of a subgroup to be invariant under conjugation within the parent group, which is a fundamental concept in abstract algebra and the study of symmetric structures.
