What Is the Right Normal Factor Semidirect Product Entity?
Right Normal Factor Semidirect Product (⋊) is the Mathematical Operators character at Unicode U+22CA (RIGHT NORMAL FACTOR SEMIDIRECT PRODUCT). It is used in group theory and algebra for semidirect product notation (for example, H ⋊ N).
Remember
Character ⋊
Unicode U+22CA
Hex entity ⋊
Decimal ⋊
Named entity ⋊
CSS escape \22CA
Not the same ⋉ (⋉) · × (×) · ⋈ (⋈)
All of these produce the same glyph: ⋊. Prefer ⋊ when you want an explicit entity (easy to mix up with ⋉ / ×).
Using Hex Code: ⋊
Using HTML Code: ⋊
Using Named Entity: ⋊
Using CSS Entity: ⋊
H ⋊ N
How It Works
1. Hex:U+22CA → ⋊ in HTML. The browser turns it into ⋊.
2. Decimal: same code point as 8906 → ⋊. Same result as hex.
3. Named:⋊ is the HTML5 name for this character.
4. CSS: use \22CA in content (not an HTML entity). #point::after appends that ⋊ after the paragraph text.
Pitfalls & Tips
Common mistakes when working with Right Normal Factor Semidirect Product.
Look-alikes
⋊ ≠ ⋉ ≠ ×
⋊ (right), ⋉ (left), and × (multiplication) are different characters.
Name
⋊ ≠ ⋉ ≠ ×
Use the exact spelling ⋊. Nearby names map to different Unicode points.
Fonts
Glyph may be missing
Mathematical Operators coverage varies. Test on your target devices or provide a fallback font.
CSS vs HTML
Do not mix escapes
\22CA belongs in CSS. ⋊ / ⋊ / ⋊ belong in HTML.

Add nearby words
Pair the glyph with equation text (for example, H ⋊ N) or use aria-label when it stands alone.
Semicolon
End references
Always finish with ; — write ⋊, not &rtimes.
Compatibility
Browser Support
Right Normal Factor Semidirect Product (U+22CA) and its entity forms (⋊, ⋊, ⋊, CSS \\22CA) are supported in all modern browsers. Glyph coverage depends on the font.

Bottom line: Prefer ⋊ for readable HTML. Use \\22CA only inside CSS content.
Remember
Key Takeaways
Unicode: this symbol is U+22CA (decimal 8906).
HTML: prefer ⋊ — or use ⋊ / ⋊.
Use ⋊ (named), ⋊ (hex), ⋊ (decimal), or the CSS escape \22CA in the content property. You can also type ⋊ directly in UTF-8 HTML.
U+22CA (RIGHT NORMAL FACTOR SEMIDIRECT PRODUCT). Hex 22CA, decimal 8906. It belongs to the Mathematical Operators block (U+2200–U+22FF).
Yes. ⋊ is the HTML5 named entity. You can also use ⋊ or ⋊. Do not confuse ⋊ with ⋉ (left) or × (multiplication).
Use it in group theory and abstract algebra when you need the right normal factor semidirect product operator (often written H ⋊ N). Prefer ⋊ for readable HTML.
HTML entities (⋊, ⋊, or ⋊) go in markup. The CSS escape \22CA is used in stylesheets (usually in the content property of ::before/::after). Both render ⋊.
⋉ (U+22C9) is the left normal factor semidirect product. × (U+00D7) is the multiplication sign. ⋊ (U+22CA) is the right normal factor form.
🤔
Did you know?
Right Normal Factor Semidirect Product is Unicode U+22CA (decimal 8906) — RIGHT NORMAL FACTOR SEMIDIRECT PRODUCT. HTML5 provides ⋊. Prefer it for readable source. Do not confuse it with ⋉ (U+22C9, left normal factor) or × (U+00D7, multiplication sign).
