We construct the color-spin wave functions of the triply-heavy pentaquarks and use the numerical variational method to compute all the ground-state masses of these systems. By excluding the scattering states in configuration spsce, we computed the decay width ratios of each decay channel relative to the maximum width for the compact pentaquark states, obtaining the main decay modes of the triply-heavy pentaquark systems."> Masses and decays of triply-heavy pentaquarks -
