HTML Entity for Not Normal Subgroup Of (⋪)
What You'll Learn
How to display the Not Normal Subgroup Of symbol (⋪) in HTML using named, hexadecimal, decimal, and CSS escape methods. This group-theory operator states that one group is not a normal subgroup of another (e.g. H ⋪ G means H is not a normal subgroup of G).
This character is U+22EA (DOES NOT CONTAIN AS NORMAL SUBGROUP) in the Mathematical Operators block (U+2200–U+22FF). Render it with the named entity ⋪, ⋪, ⋪, or CSS escape \22EA. Compare with Normal Subgroup Of (⊳, ⊳) and Normal Subgroup (⊲, ⊲).

<style>
#point::after{
content: "\22EA";
}
</style>

🧠 How It Works
Named Entity
⋪ is the HTML named entity for U+22EA—the most readable choice when writing group-theory markup.
Hexadecimal Code
⋪ uses the Unicode hexadecimal value 22EA to display the not-normal-subgroup symbol.
Decimal HTML Code
⋪ uses the decimal Unicode value 8938 to display the same character.
CSS Entity
\22EA is used in CSS stylesheets, particularly in the content property of pseudo-elements like ::before and ::after.
Same visual result
All four methods produce: ⋪. Unicode U+22EA in Mathematical Operators (U+2200–U+22FF).
Use Cases
The ⋪ symbol (⋪) is commonly used in:
Expressing that a subgroup is not normal in a given group.
Textbooks, papers, and lecture notes on groups and subgroups.
Formal proofs and definitions involving normal subgroups.
Cryptography and algebra courses covering group structures.
Interactive math modules with web-based notation.
Unicode charts and HTML entity documentation for math symbols.
💡 Best Practices
Do
- Use
⋪for readable group-theory markup - Distinguish ⋪ from ⊳ (normal subgroup of) and ⋬ (not normal subgroup or equal)
- Pair ⋪ with plain-language description on first use
- Add
aria-labelfor standalone relation symbols - Serve pages with UTF-8 (
<meta charset="utf-8">)
Don’t
- Confuse ⋪ (
⋪) with ⊳ (⊳) - Confuse ⋪ with ⋬ (
⋬, not normal subgroup or equal) - Use padded Unicode notation like U+022EA—the correct value is
U+22EA - Put CSS escape
\22EAin HTML text nodes - Use
\022EAin CSS—the correct escape is\22EA
