AB  - We report on the role of the heavy quark symmetry (HQS) in understanding the hidden charm pentaquarks, P<sub>c</sub><sup>+</sup>(4380) and P<sub>c</sub><sup>+</sup>(4450), observed by LHCb in Λ<sub>b</sub><sup>0</sup> → J/ψ  p  K<sup>−</sup> decays, in the compact diquark-diquark-antiquark picture. In the HQS-limit, only the state P<sub>c</sub><sup>+</sup>(4450) is expected to be produced. Within this picture, we employ SU(3)<sub>F</sub> symmetry to discuss the mass spectrum and decays of the related pentaquark states ―c[cq][q′q<sup>′′</sup>] with q, q<sup>′</sup>, q<sup>′′</sup>  ∈ [u,d,s]. Some of these pentaquarks are expected to be produced in b-baryon decays and we work out their relative decay widths.
