Not square image of equal to (⋢) is the Mathematical Operators character at Unicode U+22E2 (NOT SQUARE IMAGE OF OR EQUAL TO). It negates the square-image-of-or-equal relation (⊑, ⊑) used in order theory and formal mathematics.
Remember
Character ⋢
Unicode U+22E2
Named entity ⋢
Hex entity ⋢
Decimal ⋢
CSS escape \22E2
Affirmative ⊑ (⊑, U+2291)
Named, hex, decimal, CSS, and a typed character all produce the same glyph: ⋢. Prefer ⋢ in HTML source for clarity.
Using Named Entity: ⋢
Using Hex Code: ⋢
Using HTML Code: ⋢
Using CSS Entity: ⋢
Example: a ⋢ b
How It Works
1. Named:⋢ is the clearest HTML form and renders ⋢.
2. Hex:U+22E2 → ⋢ in HTML. Same result as the named entity.
3. Decimal: same code point as 8930 → ⋢. Same result as hex.
4. CSS: use \22E2 in content (not an HTML entity). #point::after appends that ⋢ after the paragraph text.
Pitfalls & Tips
Common mistakes when working with this relation symbol.
Pair
⋢ ≠ ⊑
⋢ is the negation. ⊑ is the affirmative square image of or equal (⊑).
Look-alikes
Not ⋣ or ≠
⋣ is the original-side negation (⋢ vs ⋣). ≠ is ordinary ≠ — a different operator.
CSS vs HTML
Do not mix escapes
\22E2 belongs in CSS. ⋢ / ⋢ / ⋢ belong in HTML.
Fonts
Glyph coverage
Some fonts omit Mathematical Operators. If ⋢ looks like a box, switch to a math-capable font.
Encoding
Declare UTF-8
If you paste ⋢ directly, keep <meta charset="UTF-8"> so the file is not misread.
Semicolon
End references
Always finish with ; — write ⋢, not &nsqsube.
Compatibility
Browser Support
Not square image of equal to (U+22E2) and its entity forms (⋢, ⋢, ⋢, CSS \\22E2) are supported in all modern browsers. Glyph availability depends on the font.
✓ Universal encoding
Not Square Image Of Equal To (⋢)
Encode with named, hex, decimal, or CSS escape — or paste ⋢ directly in UTF-8 HTML.

Bottom line: Prefer ⋢ for readable HTML. Use \\22E2 only inside CSS content.

Key Takeaways
Unicode: this character is U+22E2 (decimal 8930).
HTML: prefer ⋢ — or use ⋢ / ⋢.
Use ⋢ (named), ⋢ (hex), ⋢ (decimal), or the CSS escape \22E2 in the content property. All render ⋢. Prefer ⋢ in HTML source.
U+22E2 (NOT SQUARE IMAGE OF OR EQUAL TO). Hex 22E2, decimal 8930. It belongs to the Mathematical Operators block (U+2200–U+22FF).
Yes. ⋢ is the HTML5 named entity for ⋢. Related: ⊑ for ⊑ (U+2291) and ⋣ for ⋣ (U+22E3).
Use it in order theory, relation algebra, and formal mathematics when you need to negate the square-image-of-or-equal relation (⊑). Prefer ⋢ for readable source.
HTML entities (⋢, ⋢, or ⋢) go in markup. The CSS escape \22E2 is used in stylesheets (usually in the content property of ::before/::after). Both render ⋢.
⊑ (⊑, U+2291) is the affirmative square image of or equal relation. ⋢ (⋢) is its negation. ≠ (≠, U+2260) is ordinary inequality — a different operator.
🤔
Did you know?
Not square image of or equal to (⋢) is Unicode U+22E2 (decimal 8930) in Mathematical Operators. HTML5 provides ⋢ — the most readable form. It negates square image of or equal to (⊑, ⊑, U+2291). The paired original-side negation is ⋣ (⋣, U+22E3).
