Gauss notation[edit]
Originally proposed at Wikidata:Property proposal/Natural science
| Description | Gauss notation for knots |
|---|---|
| Represents | Gauss notation (Q96755115) |
| Data type | Mathematical expression |
| Domain | knot (Q1188853) |
| Allowed values | -?[0-9]+(, -?[0-9]+)* |
| Example 1 | unknot (Q1188344) → no value |
| Example 2 | trefoil knot (Q168620) → 1, -2, 3, -1, 2, -3 |
| Example 3 | figure-eight knot (Q168697) → -1, 2, -3, 1, -4, 3, -2, 4 |
| Example 4 | Kinoshita–Terasaka knot (Q94827585) → -1, 2, -3, 1, -4, 5, -2, 3, 6, -7, 8, 4, -5, -9, 7, -10, 11, -6, 9, -8, 10, -11 |

| Planned use | to add these values to entries for knots on Wikidata |
| Expected completeness | always incomplete (Q21873886) |
| See also | Dowker-Thistlethwaite notation (P8378) |
| Single-value constraint | yes |
| Wikidata project | WikiProject Mathematics (Q8487137) |
Motivation[edit]
This is a mathematical invariant for knots. While this is available in external databases, it also belongs here on Wikidata. The Anome (talk) 12:27, 13 July 2022 (UTC)
Discussion[edit]

Support We have other knot invariants, we should have this one also. ArthurPSmith (talk) 20:54, 13 July 2022 (UTC)
- Note: I've tightened the domain for this property proposal to knot (Q1188853), rather than just 'item'. This shouldn't affect the rest of the proposal. The Anome (talk) 11:56, 23 July 2022 (UTC)
