I am a mathematician. I primarily edit mathematics articles, with bouts of other stuff thrown in at random. Here are some things:

• If you like wikipedia, you might also like http://www.openstreetmap.org.
• Number of times I have deleted ANI: 1
• If you are interested in collaborating on improving the articles Catalan number, Plane partition, or Rank–nullity theorem, or anything broadly related to Permutations or the Symmetric group, let me know.

On 10 May 2021, Did you know was updated with a fact from the article Affine symmetric group. The fact was ... that juggling patterns can be encoded in terms of a mathematical object called the affine symmetric group?
