Not normal subgroup of (⋪) is the Mathematical Operators character at Unicode U+22EA (NOT NORMAL SUBGROUP OF). It states that a subgroup is not normal — for example H ⋪ G.
Using Named Entity: ⋪
Using Hex Code: ⋪
Using HTML Code: ⋪
Using CSS Entity: ⋪
Example: H ⋪ G
How It Works
1. Named:⋪ (or ⋪) is the clearest HTML form and renders ⋪.
2. Hex:U+22EA → ⋪ in HTML. Same result as the named entity.
3. Decimal: same code point as 8938 → ⋪. Same result as hex.
4. CSS: use \22EA in content (not an HTML entity). #point::after appends that ⋪ after the paragraph text.
Pitfalls & Tips
Common mistakes when working with the not-normal-subgroup-of entity.
Pair
⋪ ≠ ⊲
⋪ is the negation. ⊲ is the affirmative normal subgroup of (◃).
Look-alikes
Not ⊄ or ⋬
⊄ is ⊄ (not a subset). ⋬ is ⋬ (not normal subgroup of or equal to). Pick the exact relation.
Aliases
⋪ = ⋪
Both (and ⋪) map to U+22EA. Pick one and stay consistent.
CSS vs HTML
Do not mix escapes
\22EA belongs in CSS. ⋪ / ⋪ / ⋪ belong in HTML.
Encoding
Declare UTF-8
If you paste ⋪ directly, keep <meta charset="UTF-8"> so the file is not misread.
Semicolon
End references
Always finish with ; — write ⋪, not &nltri.
Compatibility
Browser Support
Not normal subgroup of (U+22EA) and its entity forms (⋪, ⋪, ⋪, CSS \\22EA) are supported in all modern browsers. Glyph availability depends on the font.
✓ Universal encoding
Not Normal Subgroup Of (⋪)
Encode with named, hex, decimal, or CSS escape — or paste ⋪ directly in UTF-8 HTML.

Bottom line: Prefer ⋪ (or ⋪) for readable HTML. Use \\22EA only inside CSS content.
Remember
Key Takeaways
Unicode: this character is U+22EA (decimal 8938).
HTML: prefer ⋪ (alias ⋪) — or use ⋪ / ⋪.
Use ⋪ or ⋪ (named), ⋪ (hex), ⋪ (decimal), type ⋪ in UTF-8, or the CSS escape \22EA in content. All render ⋪. Prefer ⋪ in HTML source.
U+22EA (NOT NORMAL SUBGROUP OF). Hex 22EA, decimal 8938. It belongs to the Mathematical Operators block (U+2200–U+22FF).
Yes. HTML5 defines ⋪, ⋪, and ⋪ (aliases for the same character). Related: ⊲ for ◃ (U+22B2).
Use it in group theory when H is not a normal subgroup of G (e.g. H ⊀ G). Prefer ⋪ for readable source. For the affirmative relation use ⊲ (◃).
HTML entities (⋪, ⋪, or ⋪) go in markup. The CSS escape \22EA is used in stylesheets (usually in the content property of ::before/::after). Both render ⋪.
◃ (U+22B2, ⊲) means is a normal subgroup of. ⊈ (U+2288, ⊈) means neither a subset of nor equal to. ⋪ (⋪) specifically means not a normal subgroup of — do not substitute one for another.
🤔
Did you know?
Not normal subgroup of (⋪) is Unicode U+22EA (decimal 8938) — NOT NORMAL SUBGROUP OF in Mathematical Operators. HTML5 provides ⋪, ⋪, and ⋪ (same glyph). It negates normal subgroup of (⊲, ⊲, U+22B2). Related: ⋬ (⋬, not normal subgroup of or equal to).
