My school ran out of math classes for me to take early on, and thus most of my mathematical knowledge comes from online bits, intuition, paper, a pencil, and a lot of time without anything to do. Thus, I often use a notation that is likely incorrect, such as using f [2] (x) to mean f(f(x)), along with other bits I came up with on my own that is almost certainly already used. Like Mobius Cubes, and Primal Classes. I am quite interested in four-dimensional topology, but also enjoy some number theory.
