(n - 1)(n - 1) - 1 covers the top the triangles. This actually gives us a new equation, if I'm not mistaken. But what's the deal with jumping between these different patterns? First we talk about triangles, then we talk about -f, e and then we talk about QFT? It feels like we're being dragged between multiple solutions, a way to keep the project going? A way to prevent a single solution to come out, but have them all ready at the same time? I don't quite get it.
