Basins of attraction of the map (5) in the region {(x,y)|x∈[–2.5, 2.5], y∈[–30, 30]}. Unbounded basin of attraction which is the set of initial points going into the region ({(x,y)||x|+|y|>100}) is shown in cyan, the coexisting chaotic attractors are shown in black dots. The basins of chaotic attractors are shown in red, light red, blue, light blue, green, light green, brown, magenta, and light megenta, respectively.
