Distinguishing coloring
[edit]
Distinguishing coloring of a 6-key ring
- ... that six or more keys on a keyring can be distinguished from each other by coloring the keys using only two colors (pictured), but rings of fewer keys require more colors?

Age, length, neutrality fine (do we do POV maths articles? Are there Pi-deniers?); no copyvio or plagiarism from the sources that I can access; the sources almost made my head explode and this article only gave me a mild headache, so they can't be closely paraphrased; lovely QPQ; hook intriguing; hook fact cited; photo free of restrictions and clearly visible at DYK size; paintwork on the keys is a bit sloppy, but that's not a DYK criterion, so we'll have to let that pass. Good to go. Belle (talk) 10:43, 10 August 2015 (UTC)
- Thanks! Re the π-deniers: Yes, they exist. Try looking up tauism. Or for a quck start you could try Vi Hart's videos on the subject, such as https://www.youtube.com/watch?v=5iUh_CSjaSw —David Eppstein (talk) 04:05, 12 August 2015 (UTC)
