We analytically and numerically demonstrate the existence of Hermite-Bessel-Gaussian spatial soliton clusters in three-dimensional strongly nonlocal *** is found that the soliton clusters display the vortex,dipole azimuthon and quadrupole azimuthon in geometry,and the total number of solitons in the necklaces depends on the quantum number n and m of the Hermite functions and generalized Bessel *** numerical simulation is basically identical to the analytical solution,and white noise does not lead to collapse of the soliton,which confirms the stability of the soliton *** theoretical predictions may give new insights into low-energetic spatial soliton transmission with high fidelity.
