Not Normal Subgroup Of Symbol
⋪ denotes that a subgroup is not a normal subgroup of a group.
U+22EA
⋪ is a mathematical symbol used to express a “not normal subgroup of” relationship. It’s commonly found in group theory writing and typed equations. Copy it into your notes, documents, or code with the provided escapes.
Not Normal Subgroup Of Symbol Meaning
⋪ means “not normal subgroup of.” In group theory, a subgroup H of a group G is called normal when it satisfies conjugation invariance; ⋪ is used when that normality condition does not hold. For example, you might write “H ⋪ G” (in the intended mathematical reading) to state that H is a subgroup of G but is not normal in G. This symbol is specific to advanced algebra contexts, so it appears mostly in textbooks, homework solutions, and formal derivations involving conjugation and quotient structures.
Common uses
- •Stating in group theory that a subgroup is not normal within a given group
- •Annotating proofs and exercises about conjugation and invariance
- •Writing typed algebra notes in LaTeX-like workflows (as a Unicode symbol)
- •Adding correctness checks in math-centered documentation or tutorials
- •Labeling relationships in diagrams or structured descriptions of group actions
Examples
⋪ Not Normal Subgroup Of
- ⋪Let H be a subgroup of G with H ⋪ G.
- ⋪Show that K ⋪ N by checking conjugation invariance.
- ⋪In this example, the subgroup H is not normal, written using ⋪.
- ⋪We have A ⋪ G, so the quotient construction does not apply.
- ⋪Verify that H ⋪ G before using any results that require normality.

FAQ
What does ⋪ mean?
⋪ is the “not normal subgroup of” symbol, used to indicate a subgroup is not normal in a group.
Where is ⋪ typically used?
It’s mainly used in group theory and other algebra notes involving normality and conjugation.
How can I copy ⋪ into my work?
Copy the character directly from this page, or use the HTML entity (⋪), CSS escape (\\22EA), or JavaScript escape (\\u{22EA}).
Is ⋪ the same as “normal subgroup of”?
No. ⋪ explicitly indicates the subgroup is not normal, rather than normal.
