General: Article is new enough and long enough

QPQ: Done.

Overall:

Over 5x expansion. Neutral with a good range of sources. Earwig shows 20% for one source but this does not look problematic - it's a short section about edge lengths, which possibly got to the other source by being copied from Wikipedia initially. QPQ was completed. BennyOnTheLoose (talk) 12:02, 5 March 2020 (UTC)[reply]
