A recent challenge (A Rather Knotty Conundrum) added the knot-theory tag. No previous knot theory challenges use this tag yet. Before I consider using the tag, I want to see if the tag is really necessary. This tag might make sense on Math.SE, but it seems pretty specific for our use on PPCG, and there are only three or four existing challenges that could deserve the tag:
- "KNOT" or "NOT"?
- A Rather Knotty Conundrum
- Gasket Weaving - draw a Sierpiński knot
- ASCII Art of the Day #1 - Double Knot (probably not)
Should we remove this tag, or keep it (and tag the existing challenges)?
