The following movies are periodic solutions bifurcated from the figure-eight choreographic solutions to the equation of motion \[ \frac{d^2 q_i}{dt^2} = - \frac{\partial U}{\partial q_i}, \; i = 0,1,2. \] Periods \( T \)'s of the movies are relatively correct. See arXiv:1901.00115 on initial conditions.
