This system \ncan be mapped onto an anisotropic spin-2 chain when the ferromagnetic \ninteraction is much stronger than the antiferromagnetic interaction. \nSince there are many quantum parameters in this system, we numerically \nobtained the GSPD on the plane of the magnitude of the antiferromagnetic \ncoupling versus its XXZ anisotropy, by use of the exact diagonalization, \nthe level spectroscopy as well as the phenomenological renormalization \ngroup. The obtained GSPD consists of six phases. They are the XY1, the \nlarge-D (LD), the intermediate-D (ID), the Haldane (H), the spin-1 \nsinglet dimer (SD), and the Néel phases. Among them, the LD, the H, and \nthe SD phases are the trivial phases, while the ID phase is the symmetry\n-protected topological phase. The former three are smoothly connected \nwithout any quantum phase transitions. It is also emphasized that the ID \nphase appears in a wider region compared with the case of the GSPD of \nthe anisotropic spin-2 chain with the XXZ and the on-site anisotropies.
