The antiquark-diquark-diquark model describes pentaquark states both in termsof quarks and hadrons. We discuss pentaquark states with hidden charm $P(\bar ccuud)$ discovered in the $J/\Psi p$ spectrum by the LHCb collaboration. Weconsider three pentaquark states as members of the lowest ($S$-wave) multipletand discuss the mass splitting scheme. The latest LHCb data for pentaquarkswith hidden charm provide an opportunity to make an assumption about thediquark content of the pentaquark states. We give a classification for the LHCbpentaquarks and define recombination channels for these states.
