I've found a citation of my own work on Wikipedia for the first time!
https://en.wikipedia.org/wiki/Commutative_magma
Naturally, I read this page before I wrote my rock-paper-scissors paper. It's neat to see that my own work is now the citation for something that was unsourced "original research" on Wikipedia.

How did you notice?
@keithnator3000 I was on this journal page (https://link.springer.com/article/10.1007/s00012-020-00667-5) and saw that Altmetric said there was a Wikipedia reference. After a couple guesses I found the article.
