Figure 3: Contour plot of the Bianchi type IX potential $V$ , where $β ±$ are the anisotropy canonical coordinates. Seven level surfaces are shown at equally spaced decades ranging from 10^–1 to 10⁵. For large isocontours ( $V > 1$ ), the potential is open and exhibits a strong triangular symmetry with three narrow channels extending to spatial infinity. For $V < 1$ , the potential closes and is approximately circular for $β ± ≪ 1$ .
