Does not succeed or equal (⋡) is the Unicode character at U+22E1 in the Mathematical Operators block. Official name: DOES NOT SUCCEED OR EQUAL. In order theory, a ⋡ b means a does not succeed or equal b.

Prefer ⋡ in HTML markup (aliases: &nsucccurlyeq;, ⋡). You can also type ⋡ in UTF-8, or use numeric forms when needed.

How It Works
1. Named:⋡ is the HTML5 name for U+22E1 → ⋡. Best default in markup.
2. Hex:U+22E1 → ⋡ in HTML. Same glyph as the named form.
3. Decimal: same code point as 8929 → ⋡. Same result as hex and named.
4. CSS: use \22E1 in content (not an HTML entity). #point::after appends that ⋡ after the paragraph text.
5. Typed / example: paste ⋡ in UTF-8, or write a ⋡ b. The positive form is ≽ (≽).
Pitfalls & Tips
Common mistakes when working with Does Not Succeed Or Equal.
≽
Positive vs negation
Use ≽ (≽) for succeeds or equal. Use ⋡ (⋡) for the negation.
⊁
Or-equal vs strict
Use ⊁ (⊁) for strict does not succeed. Use ⋡ when or-equal is intended.
⋠
Succeed vs precede
⋠ (⋠) is does not precede or equal. Do not swap it with ⋡.
CSS vs HTML
Do not mix escapes
\22E1 belongs in CSS strings. ⋡ / ⋡ / ⋡ belong in HTML.
Fonts
Math font coverage
Some fonts omit U+22E1. Prefer a font with Mathematical Operators coverage for display.
Semicolon
End references
Always finish with ; — write ⋡, not &nsccue.
Compatibility
Browser Support
Does not succeed or equal (U+22E1) and its entity forms (⋡, ⋡, ⋡, CSS \\22E1) are supported in all mainstream browsers. Visible glyphs depend on math font coverage.
✓ Universal support

Bottom line: Prefer ⋡ in HTML. Use ⋡ or ⋡ when numeric form is required, and \\22E1 only inside CSS content.
Remember
Key Takeaways
Unicode: does not succeed or equal is U+22E1 (decimal 8929) — glyph ⋡.
HTML: prefer ⋡, or use ⋡ / ⋡ / type ⋡.
CSS: use \22E1 inside content for generated text.
Meaning:⋡ = does not succeed or equal — not ≽, ⊁, or ⋠.
One line:U+22E1 → ⋡ / ⋡ / ⋡ / CSS \22E1 / type ⋡.
Frequently Asked Questions
Use ⋡ (named), ⋡ (hex), ⋡ (decimal), type ⋡ directly in UTF-8, or the CSS escape \22E1 in content. Prefer ⋡ in normal HTML.
U+22E1 (DOES NOT SUCCEED OR EQUAL). Hex 22E1, decimal 8929. It belongs to the Mathematical Operators block (U+2200–U+22FF).
Yes. Use ⋡ (preferred), or aliases &nsucccurlyeq; and ⋡. Numeric forms ⋡ and ⋡ also work.
Use it in order theory when a does not succeed or equal b (a ⋡ b). For the positive relation, use U+227D (≽). For strict does not succeed, use U+2281 (⊁).
HTML entities (⋡, ⋡, or ⋡) go in markup. The CSS escape \22E1 goes in stylesheet strings (usually content on ::before/::after).
No. ⋡ (⋡) is the succeeds or-equal negation. ≽ (≽) is succeeds or equal. ⋠ (⋠) is does not precede or equal.

Did you know?
Does not succeed or equal is Unicode U+22E1 (decimal 8929) — glyph ⋡ in the Mathematical Operators block. HTML5 names it ⋡ (also &nsucccurlyeq;, ⋡). It is the negation of succeeds or equal to ≽ (≽). The precede counterpart is ⋠ (⋠).
