Dynamics of the translation components $(p_1,p_2)$ of the fractional-order system (15): (a) Coexisting hidden chaotic attractor ($q=0.996$, $a=0.35$, $(x,y,z)=(1,1,1)$) with an asymptotic growth rate $K=0.9975$; (b) coexisting hidden periodic attractor ($q=0.996$, $a=0.35$, $(x,y,z)=(0,75,-50)$ with $K=0.0364$.
