Normal subgroup (⊲) is the Mathematical Operators character at Unicode U+22B2 (NORMAL SUBGROUP OF). In group theory, H ⊲ G means H is a normal subgroup of G. HTML5 provides the named entities ⊲ and ⊲.
Remember
Character ⊲
Unicode U+22B2
Named entity ⊲ (also ⊲)
Hex entity ⊲
Decimal ⊲
CSS escape \22B2
All of these produce the same glyph: ⊲. Prefer ⊲ for readable HTML; paste ⊲ in UTF-8 when convenient.

<!DOCTYPE html>
<html lang="en">
<head>
<meta charset="UTF-8">

<style>
#point::after {

Using Named Entity: ⊲
Using Hex Code: ⊲
Using HTML Code: ⊲
Using Direct Character: ⊲
Using CSS Entity: ⊲
Example: H ⊲ G
How It Works
1. Named:⊲ (or ⊲) is the clearest HTML form for U+22B2.
2. Hex:U+22B2 → ⊲ in HTML. Reliable numeric form.
3. Decimal: same code point as 8882 → ⊲. Same glyph.
4. Direct: paste ⊲ in a UTF-8 file with <meta charset="UTF-8">.
5. CSS: use \22B2 in content (not an HTML entity). #point::after appends that ⊲ after the paragraph text.
Pitfalls & Tips
Common mistakes when working with this algebra entity.
Direction
⊲ vs ⊳
H ⊲ G means H is a normal subgroup of G. The reverse symbol is ⊳ (U+22B3).
Not subset
Not ⊂
Subset ⊂ is set inclusion. Normal subgroup is a group-theory relation — different meaning.
Aliases
⊲ = ⊲
Both named forms map to U+22B2. Pick one and stay consistent.
CSS vs HTML
Do not mix escapes
\22B2 belongs in CSS. ⊲ / ⊲ / ⊲ belong in HTML.
Semicolon
End references
Always finish with ; — write ⊲, not &vltri.
UTF-8
Declare charset
If you paste ⊲ directly, serve the page as UTF-8 with <meta charset="UTF-8">.
Compatibility
Browser Support
Normal subgroup (U+22B2) and its entity forms (⊲, ⊲, ⊲, CSS \\22B2) are supported in all mainstream browsers. Glyph availability depends on the font.
✓ Universal support
Normal Subgroup (⊲)
Prefer ⊲, or encode with hex, decimal, or CSS escape — same glyph everywhere.

Bottom line: Prefer ⊲ (or ⊲) in HTML. Use ⊲ / ⊲ when a numeric form is required, and \\22B2 only inside CSS content.

Key Takeaways
Unicode: normal subgroup of is U+22B2 (decimal 8882), Mathematical Operators.
HTML: prefer ⊲ (alias ⊲), or ⊲ / ⊲.
Use ⊲ or ⊲ (named), ⊲ (hex), ⊲ (decimal), type ⊲ in UTF-8, or the CSS escape \22B2 in content. All render ⊲.
U+22B2 (NORMAL SUBGROUP OF). Hex 22B2, decimal 8882. It belongs to Mathematical Operators and is used in group theory for “is a normal subgroup of”.
Yes. HTML5 defines ⊲ and ⊲ (aliases for the same character). You can also use ⊲ or ⊲.
Use it in abstract algebra when writing H ⊲ G (H is a normal subgroup of G). Prefer ⊲ for readable source. For ordinary English, write “is a normal subgroup of” in words.
HTML entities (⊲, ⊲, or ⊲) go in markup. The CSS escape \22B2 is used in stylesheets (usually in the content property of ::before/::after). Both render ⊲.
U+22B3 (⊳) is the reverse relation (contains as normal subgroup). Subset ⊂ (U+2282, ⊂) is set inclusion, not the normal-subgroup relation. Do not substitute one for another.

Did you know?
Normal subgroup (⊲) is Unicode U+22B2 (decimal 8882) — NORMAL SUBGROUP OF in Mathematical Operators. HTML5 provides ⊲ (also ⊲). In group theory, H ⊲ G means H is a normal subgroup of G. The reverse relation is U+22B3 (⊳).
