Figure 3: Contour plot of the Bianchi type IX potential V , where b ± are the anisotropy canonical coordinates. Seven level surfaces are shown at equally spaced decades ranging from -1 10 to 5 10 . 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 b ± « 1 .
