Hey all, the group theory thing reminds me a lot of cyclic groups or ideals generated by the value 2. Also equivalence classes (which come up in group theory) can be written with [brackets] but may be confused with <cyclic groups> or (ideals). | Hey all, the group theory thing reminds me a lot of cyclic groups or ideals generated by the value 2.

Hello people. Anyone got an explanation for this? 172.70.114.229 22:59, 2 May 2022 (UTC)
To the person who has requested a citation that two is a number... here you go: https://youtu.be/dBVoIUASFS0?t=82. Can someone who knows how to add citations add it? :D --172.70.110.209 23:09, 2 May 2022 (UTC)
