HTML Entity for Intercalate (⊺)
What You'll Learn
How to display the Intercalate symbol (⊺) in HTML using hexadecimal, decimal, named entity, and CSS escape methods. This operator appears in mathematics and logic for intercalation—a binary operation used in certain algebraic structures, type theory, and formal notation.
It is U+22BA (INTERCALATE) in the Mathematical Operators block (U+2200–U+22FF). Render it with ⊺, ⊺, ⊺, or CSS \22BA. Do not confuse ⊺ with ⊻ (XOR / veebar) or ∫ (integral).

🧠 How It Works
Hexadecimal Code
⊺ uses the Unicode hexadecimal value 22BA to display the Intercalate symbol. The x prefix indicates hexadecimal format.
Decimal HTML Code
⊺ uses the decimal Unicode value 8890 to display the same character.
CSS Entity
\22BA is used in CSS stylesheets, particularly in the content property of pseudo-elements like ::before and ::after.
Named Entity
⊺ is the standard named HTML entity for intercalate—mnemonic for “intercalate” and easy to read in source.
Same visual result
All four methods produce ⊺. Unicode U+22BA is in Mathematical Operators. Next: Interlocked Female Male Sign.
Use Cases
The Intercalate symbol (⊺) is commonly used in:
Intercalation product and related binary operations in algebra.
Type theory, proof assistants, and logical frameworks.
Operations in algebraic structures and category theory.
Papers in mathematics, logic, and computer science.
Formal specs and documentation that define the operator.
Languages or tools that expose intercalate-like operations.
💡 Best Practices
Do
- Use
⊺for readable source markup - Define the operator when first used on a page
- Pick one style (hex / decimal / named) per project
- Use MathML or ARIA for complex formal expressions
- Test rendering with math-friendly fonts
Don’t
- Confuse ⊺ (intercalate) with ⊻ (XOR) or ∫ (integral)
- Use CSS
\22BAinside HTML text nodes - Mix entity styles randomly in one file
- Assume readers know intercalation without context
- Rely on plain HTML for heavy subscript/superscript layout
