In his newest preon model, Carl Brannen (whose diagram I have filched) uses a total of 24 objects, including six squares as shown. In other words, think of the six squares of a permutohedron, given by the squares of a truncated octahedron. These ternary geometry type squares were rotated by 45 degrees from the squares used to specify the usual dual, namely a cube.
