In this paper, our main focus is on calculation the mass and partial decay width ratios of the triply heavy pentaquark state \(QQQn\bar{n}(Q=b,c)\). By the MIT bag model, we conduct fitting and variational calculations to obtain the mass spectrum of the \(QQQn\bar{n}\) system. By excluding scattering states based on the color-spin wave functions corresponding to the obtained masses, we derive the partial decay width ratios for the compact pentaquark states and their potential decay products. By analyzing the width ratio of different decay channels, we can get the main decay modes of the studied \(QQQn\bar{n}\) system, and get the specific characteristics of decay channels under different flavor configurations.
