What Is Does Not Contain As Normal Subgroup?
Does not contain as normal subgroup (⋫) is the Unicode character at U+22EB in the Mathematical Operators block. Official name: DOES NOT CONTAIN AS NORMAL SUBGROUP. In group theory, G ⋫ H means G does not contain H as a normal subgroup (strict).

Prefer ⋫ in HTML markup. You can also type ⋫ in UTF-8, or use numeric forms when needed.

How It Works
1. Named:⋫ is the HTML5 name for U+22EB → ⋫. Best default in markup.
2. Hex:U+22EB → ⋫ in HTML. Same glyph as the named form.
3. Decimal: same code point as 8939 → ⋫. Same result as hex and named.
4. CSS: use \22EB in content (not an HTML entity). #point::after appends that ⋫ after the paragraph text.
5. Typed / example: paste ⋫ in UTF-8, or write G ⋫ H for the strict group-theory relation.
Pitfalls & Tips
Common mistakes when working with Does Not Contain As Normal Subgroup.
⋭
Strict vs or-equal
Use ⋫ (⋫) for strict. Use ⋭ (⋭) when or-equal is intended.
⋪
Left vs right form
⋪ (⋪) is “not normal subgroup of.” ⋫ (⋫) is “does not contain as normal subgroup.”
⊳
Positive relation
Do not use ⋫ when you mean contains as normal subgroup — that is ⊳ (⊳).
CSS vs HTML
Do not mix escapes
\22EB belongs in CSS strings. ⋫ / ⋫ / ⋫ belong in HTML.
Fonts
Math font coverage
Some fonts omit U+22EB. Prefer a font with Mathematical Operators coverage for display.
Semicolon
End references
Always finish with ; — write ⋫, not &nrtri.
Compatibility
Browser Support
Does not contain as normal subgroup (U+22EB) and its entity forms (⋫, ⋫, ⋫, CSS \\22EB) are supported in all mainstream browsers. Visible glyphs depend on math font coverage.

Bottom line: Prefer ⋫ in HTML. Use ⋫ or ⋫ when numeric form is required, and \\22EB only inside CSS content.
Remember
Key Takeaways
Unicode: does not contain as normal subgroup is U+22EB (decimal 8939) — glyph ⋫.
HTML: prefer ⋫, or use ⋫ / ⋫ / type ⋫.
CSS: use \22EB inside content for generated text.
Meaning:⋫ = strict — not ⋭ (or-equal) or ⋪ (left form).
One line:U+22EB → ⋫ / ⋫ / ⋫ / CSS \22EB / type ⋫.
Frequently Asked Questions
Use ⋫ (named), ⋫ (hex), ⋫ (decimal), type ⋫ directly in UTF-8, or the CSS escape \22EB in content. Prefer ⋫ in normal HTML.
U+22EB (DOES NOT CONTAIN AS NORMAL SUBGROUP). Hex 22EB, decimal 8939. It belongs to the Mathematical Operators block (U+2200–U+22FF).
Yes. Use ⋫. Numeric forms ⋫ and ⋫ also work.
Use it in group theory and abstract algebra when a group does not contain another as a normal subgroup (strict). For the or-equal negation, use U+22ED (⋭).
HTML entities (⋫, ⋫, or ⋫) go in markup. The CSS escape \22EB goes in stylesheet strings (usually content on ::before/::after).
⋫ (U+22EB, ⋫) is strict. ⋭ (U+22ED, ⋭) includes or-equal. Use the entity that matches your notation.

Did you know?
Does not contain as normal subgroup is Unicode U+22EB (decimal 8939) — glyph ⋫ in the Mathematical Operators block. HTML5 names it ⋫. It is the strict negation of containment as a normal subgroup; the or-equal form is ⋭ (⋭, U+22ED).
