Figure 1. Solutions obtained by Darboux transformation with $a=2{\rm{i}}$, b = 1: (a) two-soliton solution ${q}_{2-0-{\rm{hyb}}}$ with parameters ${\lambda }_{1}={\rm{i}},{\lambda }_{2}=2{\rm{i}};$ (b) four-soliton solution ${q}_{4-0-{\rm{hyb}}}$ with parameters ${\lambda }_{1}={\rm{i}},{\lambda }_{2}=2{\rm{i}},{\lambda }_{3}=\tfrac{3{\rm{i}}}{2},{\lambda }_{4}=\tfrac{{\rm{i}}}{2};$ (c) a hybrid solution ${q}_{2-1-{\rm{hyb}}}$ consisting of a two-soliton and a breather with ${\lambda }_{1}=1+{\rm{i}},{\lambda }_{2}=-1+{\rm{i}},{\lambda }_{3}={\rm{i}},{\lambda }_{4}=2{\rm{i}}$.
