HTML Entity for Subgroup Or Equal To Reverse (⊵)
What You'll Learn
How to display Subgroup Or Equal To Reverse (⊵) in HTML using named, hexadecimal, decimal, and CSS escape methods. This character is U+22B5 (CONTAINS AS NORMAL SUBGROUP OR EQUAL TO) in the Mathematical Operators block (U+2200–U+22FF)—the reversed counterpart to Subgroup Equal To (⊴, ⊴).
Render it with ⊵, ⊵, ⊵, or CSS \22B5. Compare with Normal Subgroup Of (⊳, ⊳) and Normal Subgroup (⊲, ⊲).

🧠 How It Works
Named HTML Entity
⊵ is the semantic named entity for U+22B5—the most readable option in source HTML.
Hexadecimal Code
⊵ references code point U+22B5 using hex digits 22B5.
Decimal HTML Code
⊵ is the decimal equivalent (8885) for the same character.
CSS Entity
\22B5 is the CSS escape for U+22B5, used in the content property of pseudo-elements.
Same visual result
All four methods produce ⊵. Unicode U+22B5 in Mathematical Operators (U+2200–U+22FF).
Use Cases
Subgroup Or Equal To Reverse (⊵) commonly appears in:
Expressing reversed normal subgroup relations between groups.
Research articles and textbooks on abstract algebra.
Online courses and tutorials teaching group theory.
Technical documentation for mathematical notation.
Theorem statements and logical derivations in algebra.
Interactive tools displaying subgroup relation symbols.
💡 Best Practices
Do
- Prefer
⊵for readable HTML source code - Pair with
⊴(⊴) when showing both directions of a relation - Provide context or alt text for screen readers in mathematical content
- Use math-friendly fonts that support Mathematical Operators
- Pick one reference style and stay consistent per project
Don’t
- Use padded Unicode notation like U+022B5—the correct value is
U+22B5 - Use CSS
\022B5with a leading zero—prefer\22B5 - Confuse ⊵ with ⊴ (
⊴) or ⊳ (⊳) - Use the symbol outside proper mathematical or group-theory context
- Put CSS escape
\22B5in HTML text nodes
