Using the diquark and triquark Regge trajectory relations, we propose the Regge trajectory relations for the quadruply heavy pentaquark ${bb\\bar{u}cc}$: $M=2m_{b}+2m_{c}+m_{u}+5C/2 +\\beta_{x_{\\lambda}}(x_{\\lambda}+c_{0x_{\\lambda}})^{2/3}$$+\\beta_{x_{\\rho_1}}(x_{\\rho_1}+c_{0x_{\\rho_1}})^{2/3}+\\beta_{x_{\\rho_2}}\\sqrt{x_{\\rho_2}+c_{0x_{\\rho_2}}} +\\beta_{x_{\\sigma}}(x_{\\sigma}+c_{0x_{\\sigma}})^{2/3}$.
