From the sequential reference point, 1 is the cornerstone (foundation stone) of the pyramid, and is therefore set directly opposite the capstone. Together these rest in balance on the fulcrum of 5. We use this lever to manipulate the Hypercube's mechanism.
As the foundation stone of the cube, 1 is the first component of the Quaternary complex of corner positions: (1, 3, 6, 8).
There are two fundamental Quaternary complexes built into the cube. They can be formed by gathering all four corners (as above) or by gathering all the outlying middle compartments or hubs (2, 4, 5, 7)
