gamma - -2.5 figure

gamma = -2.5

This is NOT a Poincare section: the attractor is periodic (P).
The symmetry of the attractor is Z3.
Note how the reflection symmetry in the bottom figure has been lost ever so slightly.

gamma = -2.2
              gamma = -2.2 and -2.3
gamma = -2.3

gamma = -2.4
              gamma = -2.4 and -2.5
gamma = -2.5   (This figure)

gamma = -4.2765
              gamma = -4.2765 and -4.2766
gamma = -4.2766

gamma = -4.5
              gamma = -4.5 and -4.6
gamma = -4.6
