Meaning and usage
Appears in specialized infinite-cardinal notation and related set-theory literature.
Define the notation when using it because conventions are less universal than aleph notation.

Formula examples
\daleth_0How to type Daleth Symbol
- Windows
- Use Character Map and search for Daleth Symbol, or paste the Unicode character (U+2138).
- macOS
- Open Character Viewer with Control–Command–Space and search for Daleth Symbol.
- Microsoft Word
- In an equation, type \daleth and press Space when Word supports the command; otherwise insert the Unicode character.
- iPhone and iPad
- Copy and paste ℸ, or use a math/LaTeX app. The standard iOS keyboard may not expose every mathematical symbol.
- Android
- Copy and paste ℸ, or use a math keyboard or LaTeX editor. Keyboard layouts vary by device and app.
- Google Docs
- For plain text, paste ℸ or use Insert → Special characters. For structured math, use the equation editor and verify \daleth.
- Excel
- Paste ℸ into a cell or use Insert → Symbol when available. Ordinary cells preserve the character but do not interpret LaTeX commands.
Common mistakes
- Do not reuse ℸ as an unrelated variable when it denotes Daleth Symbol; define any nonstandard meaning explicitly.
- For plain text, copy ℸ as U+2138; for structured equations, use \daleth in math mode. A look-alike glyph or image can break search, accessibility, or parsing when the intended character is Daleth Symbol.
When to use ℸ
- Use ℸ in plain text when a Unicode character is appropriate and the destination preserves U+2138.
- Use \daleth in an equation editor when mathematical spacing or structure matters.
- Define the local meaning when Daleth Symbol is used in number sets, number theory with a field-specific convention.
Look-alikes and related characters
- ℵ — Aleph Symbol
- ℶ — Beth Symbol
