HTML Entity for Multiset (⊌)
What You'll Learn
How to display the Multiset symbol (⊌) in HTML using hexadecimal, decimal, and CSS escape methods. This character is U+228C (MULTISET) in the Mathematical Operators block (U+2200–U+22FF)—used in set theory and combinatorics for multiset (bag) notation.
Render it with ⊌, ⊌, or CSS escape \228C. There is no named HTML entity. This is a mathematical Unicode symbol—not a programming data structure like C++ std::multiset. Related multiset operators include Multiset Multiplication (⊍) and bag membership in Z notation (⋿).

This example demonstrates the Multiset symbol (⊌) using hexadecimal code, decimal HTML code, and a CSS content escape:
<!DOCTYPE html>
<html>
<head>
<style>
#point:after{
content: "\228C";
}
</style>
</head>
<body>
<p>Multiset using Hexadecimal: ⊌</p>
<p>Multiset using HTML Code: ⊌</p>

🧠 How It Works
Hexadecimal Code
⊌ uses the Unicode hexadecimal value 228C to display the Multiset symbol. The x prefix indicates hexadecimal format.
Decimal HTML Code
⊌ uses the decimal Unicode value 8844 to display the same character.
CSS Entity
\228C is used in CSS stylesheets, particularly in the content property of pseudo-elements like ::before and ::after.
Same visual result
All three methods produce: ⊌. Unicode U+228C in Mathematical Operators. See also Multiset Multiplication (⊍).
Use Cases
The Multiset symbol (⊌) is commonly used in:
Multiset and bag relations in mathematical notation.
Counting problems with repeated elements and bags.
Textbooks, papers, and lecture notes on discrete math.
Specification docs alongside Z notation and bag types.
Online courses and tutorials on sets and combinatorics.
Unicode charts and HTML entity documentation.
💡 Best Practices
Do
- Use numeric codes
⊌or⊌in HTML markup - Use math fonts (Cambria Math, STIX) for consistent operator glyphs
- Pair with related multiset operators when documenting notation
- Add
aria-label(e.g. “multiset”) for accessibility - Serve pages with UTF-8 (
<meta charset="utf-8">)
Don’t
- Confuse this math symbol with C++
std::multisetcontainers - Assume ⊌ means ordinary set subset without context
- Put CSS escape
\228Cin HTML text nodes - Mix entity styles randomly in one file
- Rely on the symbol alone without accessible description
