It's a bit convoluted, but, as I get, here's how it goes
First, there is boxN, with N standing for number of faces the box has. Then, there is boxN-M, M standing for number of edges removed.
Then, N and M both can have a letter after them. Each letter stands for how missing faces/edges are placed relative to eachother. Dash in boxN-M removed, if N has a modifier letter
Edge letters:
- p - edges are parallel to eachother
- a - missing edges are placed in a way that leave missing face without edges (it's hard to word, more of you know it when you see it)
Face letters:
- o - faces are opposite to eachother
- t - faces are all touching eachother (usually, it's implied, but box4t.dat is a thing)
- u - faces missing form a U shape
