• These are fantastic hooks for this article – which itself has well-sourced and neutral text, and appears to be free of copyvio. It also has great images, although those are outside the scope of this review. As the article and hooks meet DYK criteria, this is good to go! Very nicely done as usual, David Eppstein. ezlev (user/tlk/ctrbs) 21:20, 26 March 2024 (UTC)
