  In the paper, we study the production of pentaquark $\bar{c}q qqq$ from
singly bottom baryon. The tensor representations of pentaquark $\bar{c}q qqq$
are completed at first. Under the light quark symmetry analysis, we decompose
the singly charmed pentaquarks into $6$, $15$ and $15'$ multiple states, and
deduce the representations of these states. Then we construct the production
Hamiltonian of the multiple states in proper order. For completeness, we
systematically study the production channels of pentaquark states, including
the possible production amplitudes and cross section relations between
different channels. Ultimately, we screen out some advantageous channels, which
expected to be fairly valuable supports for future search experiments.
