Using a transport model coupled with a phase-space coalescence afterburner, we study the triton-{sup 3}He (t-{sup 3}He) ratio with both relative and differential transverse flows in semicentral {sup 132}Sn+{sup 124}Sn reactions at a beam energy of 400 MeV/nucleon. The neutron-proton ratios with relative and differential flows are also discussed as a reference. We find that similar to the neutron-proton pairs, the t-{sup 3}He pairs also carry interesting information regarding the density dependence of the nuclear symmetry energy. Moreover, the nuclear symmetry energy affects more strongly the t-{sup 3}He relative and differential flows than the {pi}{sup -}/{pi}{sup +} ratio in the same reaction. The t-{sup 3}He relative flow can be used as a particularly powerful probe of the high-density behavior of the nuclear symmetry energy.
