Definition

What Is the Not Normal Subgroup Of Equal To Entity?

Not Normal Subgroup Of Equal To (⋬) is the group-theory operator at Unicode U+22EC. HTML5 provides &nltrie;. Example: H ⋬ G means H is neither a normal subgroup of G nor equal to G.

Remember

Character     ⋬
Unicode       U+22EC
Named entity  &nltrie;
Hex entity    &#x22EC;
Decimal       &#8940;
CSS escape    \22EC

Named, hex, decimal, CSS, and a typed character all produce the same glyph: ⋬.

Reference

Quick Reference

One table for every form you will actually use.

Form	Code	Where it goes
Named entity	`&nltrie;`	HTML markup (preferred)
Direct character	`⋬`	UTF-8 HTML text
Hex entity	`⋬`	HTML markup
Decimal entity	`⋬`	HTML markup
CSS escape	`\22EC`	Stylesheet `content`

When to Use Which

Situation	Use
Not normal subgroup or equal	`&nltrie;`
Need an entity in HTML source	`&nltrie;`, `⋬`, or `⋬`
Generated text via `::before` / `::after`	`content: "\22EC"`
Strict not normal subgroup (⋪)	See Not Normal Subgroup Of — `&nltri;`
Opposite containment (⋭)	`&nrtrie;`

Named + Hex + Decimal + CSS

Four ways to produce ⋬ in a single document.

html

<!DOCTYPE html>
<html lang="en">
<head>
  <meta charset="UTF-8">
  <title>nltrie (⋬)</title>
  <style>
    #point::after {
      content: "\22EC";
    }
  </style>
</head>
<body>
  <p>Using Named Entity: &nltrie;</p>
  <p>Using Hex Code: &#x22EC;</p>
  <p>Using HTML Code: &#8940;</p>
  <p id="point">Using CSS Entity: </p>
  <p>Formula: H &nltrie; G</p>
</body>
</html>

Try It Yourself

How It Works

1. Named: &nltrie; is the clearest HTML form and renders ⋬.

2. Hex: U+22EC → ⋬ in HTML. Same result as the named entity.

3. Decimal: same code point as 8940 → ⋬. Same result as hex and named.

4. CSS: use \22EC in content (not an HTML entity). #point::after appends that ⋬ after the paragraph text.

Pitfalls & Tips

Common mistakes when working with this group-theory symbol.

Prefer

Use `&nltrie;`

The named form is clearer than numeric references and is defined in HTML5.

vs ⋪

Not the strict form

&nltri; is ⋪ (U+22EA). This page’s symbol includes the “or equal” negation.

vs ⋭

Not opposite containment

&nrtrie; is ⋭ (U+22ED). Do not swap left/right variants.

CSS vs HTML

Do not mix escapes

\22EC belongs in CSS. &nltrie; / ⋬ / ⋬ belong in HTML.

Encoding

Declare UTF-8

If you type ⋬ directly, keep <meta charset="UTF-8"> so the file is not misread.

Semicolon

End references

Always finish with ; — write &nltrie;, not &nltrie.

Compatibility

Browser Support

Not Normal Subgroup Of Equal To (U+22EC) and its entity forms (&nltrie;, ⋬, ⋬, CSS \\22EC) are supported in all mainstream browsers with a Unicode-capable font.

✓ Universal support

nltrie (&nltrie;)

Encode with named, hex, decimal, or CSS escape — or type ⋬ directly in UTF-8 HTML.

U+22EC / &nltrie; Full support

Bottom line: Prefer &nltrie; in math HTML. Use \\22EC only inside CSS content.

Remember

Key Takeaways

Unicode: this symbol is U+22EC (decimal 8940).
HTML: prefer &nltrie;.
CSS: use \22EC inside content for generated text.
Lookalike: not &nltri; (⋪) or &nrtrie; (⋭).

One line: U+22EC → prefer &nltrie; (also ⋬ / CSS \22EC).

Frequently Asked Questions

How do I display Not Normal Subgroup Of Equal To in HTML using entities?

Use &nltrie; (named), ⋬ (hex), ⋬ (decimal), or the CSS escape \22EC in the content property. All render ⋬. Prefer &nltrie; in math HTML.

Is there a named HTML entity for U+22EC?

Yes. HTML5 defines &nltrie; for ⋬.

When should I use this HTML entity?
