An ultracold three-species Bose-Fermi-Fermi degenerate atomic mixture 87Rb-40K-6Li was realized very recently (Tagliber M et al 2008 Phys. Rev. Lett. 100 010401). Here, we study the creation of heteronuclear triatomic molecules in this mixture, and show that a constructive triple-path interference can lead to an almost ideal conversion rate, in comparison with the single- or double-path cases. The important effect of the initial population imbalance on the atom-molecule dark state is also investigated.
