What Is Subgroup Or Equal To Reverse?

Subgroup or equal to reverse (⊵) is the Mathematical Operators character at Unicode U+22B5 (CONTAINS AS NORMAL SUBGROUP OR EQUAL TO). In group theory, G ⊵ H means G contains H as a normal subgroup or equal. HTML5 provides the named entities ⊵ and ⊵.

Remember
Character     ⊵
Unicode       U+22B5
Named entity  ⊵  (also ⊵)
Hex entity    ⊵
Decimal       ⊵
CSS escape    \22B5

All of these produce the same glyph: ⊵. Prefer ⊵ for readable HTML; paste ⊵ in UTF-8 when convenient.

Five ways to produce ⊵ in a single document.

html
<!DOCTYPE html>
<html lang="en">
<head>
  <meta charset="UTF-8">
  <title>Subgroup Or Equal To Reverse (⊵) in HTML</title>
  <style>
    #point::after {
      content: "\22B5";
    }
  </style>
</head>
<body>
  <p>Using Named Entity: &rtrie;</p>
  <p>Using Hex Code: &#x22B5;</p>
  <p>Using HTML Code: &#8885;</p>
  <p>Using Direct Character: ⊵</p>
  <p id="point">Using CSS Entity: </p>

Try It Yourself

How It Works

1. Named: &rtrie; (or &trianglerighteq;) is the clearest HTML form for U+22B5.

2. Hex: U+22B5 → &#x22B5; in HTML. Reliable numeric form.

3. Decimal: same code point as 8885 → &#8885;. Same glyph.

4. Direct: paste ⊵ in a UTF-8 file with <meta charset="UTF-8">.

5. CSS: use \22B5 in content (not an HTML entity). #point::after appends that ⊵ after the paragraph text.

Pitfalls & Tips

Common mistakes when working with Subgroup Or Equal To Reverse.

Direction

⊵ vs ⊴

G ⊵ H means G contains H as a normal subgroup or equal. The reverse symbol is &ltrie; (U+22B4).

Not ⊳

Not without “or equal”

&vrtri; (U+22B3) is contains as normal subgroup without the bar under the triangle.

Not superset

Not ⊇

Superset or equal &supe; is set inclusion. This entity is a group-theory relation — different meaning.

Aliases

&rtrie; = &trianglerighteq;

Both named forms map to U+22B5. Pick one and stay consistent.

CSS vs HTML

Do not mix escapes

\22B5 belongs in CSS. &rtrie; / &#x22B5; / &#8885; belong in HTML.

Semicolon

End references

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

Browser Support

Subgroup or equal to reverse (U+22B5) and its entity forms (&rtrie;, &#x22B5;, &#8885;, CSS \\22B5) are supported in all mainstream browsers. Glyph availability depends on the font.

✓ Universal support

Subgroup Or Equal To Reverse (&#x22B5;)

Prefer &rtrie;, or encode with hex, decimal, or CSS escape — same glyph everywhere.

Bottom line: Prefer &rtrie; (or &trianglerighteq;) in HTML. Use &#x22B5; / &#8885; when a numeric form is required, and \\22B5 only inside CSS content.

Key Takeaways

  • Unicode: this mark is U+22B5 (decimal 8885) — glyph ⊵.
  • HTML: prefer &rtrie; (alias &trianglerighteq;), or &#x22B5; / &#8885;.
  • CSS: use \22B5 inside content for generated text.
  • Meaning: G ⊵ H — not the same as ⊴, ⊳, or ⊇.

One line: U+22B5 → &rtrie; / &#x22B5; / &#8885; / CSS \22B5.

Frequently Asked Questions

Use &rtrie; (named), &#x22B5; (hex), &#8885; (decimal), type ⊵ directly in UTF-8, or the CSS escape \22B5 in content. Alias: &trianglerighteq;.
U+22B5 (CONTAINS AS NORMAL SUBGROUP OR EQUAL TO). Hex 22B5, decimal 8885. It belongs to Mathematical Operators (U+2200–U+22FF).
Yes. HTML5 defines &rtrie; and &trianglerighteq; for this character. Both are equivalent to &#8885; and &#x22B5;.
Use it in group theory when G contains H as a normal subgroup or equal (G ⊵ H). Prefer &ltrie; for the reverse relation (U+22B4) and &vrtri; for contains as normal subgroup without “or equal” (U+22B3).
HTML entities (&rtrie;, &#8885;, or &#x22B5;) go in markup. The CSS escape \22B5 goes in stylesheet strings (usually content on ::before/::after).
No. ⊵ is U+22B5 (contains as normal subgroup or equal). ⊴ is U+22B4 (normal subgroup of or equal). ⊇ is U+2287 (superset of or equal to) — set theory, not the same relation.

Did you know?

Subgroup or equal to reverse (⊵) is Unicode U+22B5 (decimal 8885) — CONTAINS AS NORMAL SUBGROUP OR EQUAL TO in Mathematical Operators. HTML5 provides &rtrie; (also &trianglerighteq;). In group theory, G&nbsp;&rtrie;&nbsp;H means G contains H as a normal subgroup or equal. The reverse relation is U+22B4 (&ltrie;).
