We employ parity-density matrix renormalization group with periodic boundary conditions. The finite-size scaling of R\\'enyi entropies $S_2$ and $S_\\infty$ are used to construct the phase diagram of the system. The phase diagram displays three possible phases: Haldane type (an example of symmetry protected topological ordered phases), Classical Dimer and N\\'eel phases, the latter bounded by two continuous quantum phase transitions.
