**Figure 1.**The domain of attraction of the map in Equation (1). This domain was obtained in floating point arithmetic. Moreover, 40,000 points obtained with initial conditions $\left(x\right(0),y(0\left)\right)$=$(-0.5,0.4)$ are shown.

**Figure 2.**In (

**a**) is shown the three correlations between the sequences $({s}_{1},{s}_{2})$, $({s}_{1},{s}_{3})$, and $({s}_{1},{s}_{4})$, and in (

**b**), between sequences $({s}_{5},{s}_{6})$, $({s}_{5},{s}_{7})$, and $({s}_{5},{s}_{8})$.

**Figure 3.**In (

**a**) is shown the three correlations between the sequences $({s}_{1},{s}_{2})$, $({s}_{1},{s}_{3})$, and $({s}_{1},{s}_{4})$, and in (

**b**), between sequences $({s}_{5},{s}_{6})$, $({s}_{5},{s}_{7})$, and $({s}_{5},{s}_{8})$; by now, the value of a in Equation (1) is changed to 1.7777777.
