What You'll Learn

How to display the Does Not Contain As Normal Subgroup Or Equal symbol (⋭) in HTML using named, hexadecimal, decimal, and CSS entity methods. This character is U+22ED in the Mathematical Operators block (U+2200–U+22FF) and expresses the “or equal” negation of normal-subgroup containment in group theory.

Render it with the named entity ⋭, ⋭, ⋭, or CSS escape \22ED. For the strict relation (⋫), see Does Not Contain As Normal Subgroup (⋫).

Complete HTML Example

This example demonstrates the symbol (⋭) using hexadecimal code, decimal HTML code, the named entity, and a CSS content escape on a pseudo-element:

html
<!DOCTYPE html>
<html>
<head>
 <style>
  #point:after{
   content: "\22ED";
  }
 </style>
</head>
<body>
<p>Using Hexadecimal: &#x22ED;</p>
<p>Using HTML Code: &#8941;</p>
<p>Using Named Entity: &nrtrie;</p>
<p id="point">Using CSS Entity: </p>
</body>
</html>

🧠 How It Works

1

Named Entity

&nrtrie; is the HTML named entity for the or-equal variant — note the final e distinguishes it from &nrtri; (strict).

HTML markup
2

Hexadecimal Code

&#x22ED; uses the Unicode hexadecimal value 22ED. The x prefix indicates hexadecimal format.

HTML markup
3

Decimal HTML Code

&#8941; uses the decimal Unicode value 8941 to display the same character.

HTML markup
4

CSS Entity

\22ED is used in CSS stylesheets, particularly in the content property of pseudo-elements like ::before and ::after.

CSS stylesheet
=

Same visual result

All four methods produce: . Unicode U+22ED is the or-equal relation. For strict ⋫, see Does Not Contain As Normal Subgroup (&nrtri;).

Use Cases

The symbol (⋭) commonly appears in the following scenarios:

∑ Group theory

Or-equal negation when G neither contains H as normal subgroup nor equals H.

📐 Math docs

Papers and textbooks distinguishing strict vs. or-equal relations.

📚 Education

University algebra courses teaching normal subgroup notation.

🔢 Symbol refs

Mathematical Operators lists and HTML entity guides.

📝 Formula pages

Web math content needing the correct or-equal Unicode glyph.

📑 Entity guides

References for research and education projects.

💡 Best Practices

Do

  • Use &nrtrie; for the or-equal variant (not &nrtri;)
  • Link to the strict page (⋫) when readers need &nrtri;
  • Use fonts that cover Mathematical Operators (U+2200–U+22FF)
  • Pair with text, MathML, or ARIA for accessibility
  • Pick one entity style per project for consistency

Don’t

  • Swap &nrtri; and &nrtrie; (different code points)
  • Use ⋭ when the strict relation ⋫ is intended
  • Use CSS escape \22ED inside HTML markup
  • Mix hex, decimal, and named styles randomly in one file
  • Rely on the symbol alone without accessible description

Key Takeaways

1

Three HTML references all render ⋭

&#x22ED; &#8941; &nrtrie;
2

For CSS stylesheets, use the escape in the content property

\22ED
3

Unicode U+22ED is the or-equal normal-subgroup non-containment relation

4

&nrtrie; ends with e; &nrtri; is the strict variant

❓ Frequently Asked Questions

Use &nrtrie; (named), &#x22ED; (hex), &#8941; (decimal), or \22ED in CSS content. All produce ⋭.
U+22ED (hex 22ED, decimal 8941) in the Mathematical Operators block. It means “does not contain as normal subgroup or equal.”
In group theory and abstract algebra when you need the or-equal negation: a group neither contains another as a normal subgroup nor is equal to it.
⋫ (U+22EB, &nrtri;) is strict. ⋭ (U+22ED, &nrtrie;) includes or-equal. Use &nrtrie; when the or-equal negation is intended.
Yes. &nrtrie; is the named entity for U+22ED (⋭). Do not confuse with &nrtri; for U+22EB.
