1

Hexadecimal Code

&#x22E4; references code point U+22E4 using hex digits 22E4.

HTML markup
2

Decimal HTML Code

&#8932; is the decimal equivalent (8932) for the same character.

HTML markup
3

CSS Entity

\22E4 is the CSS escape for U+22E4, used in the content property of pseudo-elements.

CSS stylesheet
=

Same visual result

All three methods produce . Unicode U+22E4 in Mathematical Operators (U+2200–U+22FF). No named entity.

Use Cases

Square Image Of Not Equal To (⋤) commonly appears in:

📊 Set theory

Inequality in square image and subset-like relationships.

📐 Mathematical notation

Equations and formulas using the not-equal square image operator.

📚 Academic papers

Research on order theory, logic, and abstract algebra.

🏫 Educational content

💡 Best Practices

Do

  • Use &#x22E4; or &#8932; in HTML markup
  • Distinguish ⋤ from ⊏ (square image of) and ⊑ (or equal to)
  • Add context text when the symbol stands alone in educational content
  • Pick hex or decimal style and stay consistent per project
  • Test rendering with math-friendly fonts

Don’t

  • Use padded Unicode notation like U+022E4—the correct value is U+22E4
  • Use CSS \022E4 with a leading zero—prefer \22E4
  • Expect a named HTML entity for U+22E4
  • Confuse ⋤ with ordinary not-equal ≠ (&ne;)
  • Put CSS escape \22E4 in HTML text nodes
