User:Emlightened/xkcd Notations

Directory for some of the notations created on the xkcd forums. Feel free to edit them to add an analysis, or correct errors, or anything, really. You're fine to include more, but link to the post(s) where they were introduced.

Note: Due to things that happened, some of Psi's notations' original posts are no longer available, and his notations are being recorded from memory

Misc (For some simple notations that were only used briefly.)

Psi's Letters

user's Brackets (also on user's blog)

emlightened's Brackets (also coming soon on my blog)

Vytron's Commas (the ⇑ version)

user's Up Arrow Extension

Psi's Bullet Array

Feel free to add more. This currently only covers one of the recent cancelled versions, and some misc notations. If one of the posts gets edited and the notation is no longer there, then sorry.
