  In this article, we construct the scalar-diquark-scalar-diquark-antiquark
type current to study the ground state triply charmed pentaquark states with
the QCD sum rules. We separate the contributions of the negative-parity and
positive parity triply charmed pentaquark states explicitly, and take the
energy scale formula $\mu=\sqrt{M^2_{P}-(3{\mathbb{M}}_c)^2}$ to determine the
optimal energy scales of the QCD spectral densities. The predicted pentaquark
masses can be confronted to the experimental data in the future.
