Scott Pakin’s 2017 “Comprehensive LaTeX Symbol List” is a document that lists a vast number of symbols and the corresponding LaTeX commands that produce them. The document is designed to be a convenient resource for looking up symbols.
The document lists over 14,000 symbols, so it's not feasible to list them all here. However, they cover a wide range of mathematical and scientific symbols, including (but not limited to):
- Greek letters
- Binary operators
- Relation symbols
- Arrow symbols
- Large operators
- Various mathematical functions
- Special characters and symbols
For the full list of symbols, you can refer to the document itself. It's available online at various sources, including the CTAN website and Wikimedia Commons.
