The data on the approximated high-symmetry Bravais sublattices in crystals with the In4Te3 structure are reported. The compatibility matrices are given for the derived combinations of crystal lattice and sublattices. The compatible Brillouin zones of the crystal and the sublattices are constructed. The effect of a “hidden” symmetry inherent in the crystals with the In4Te3 structure on the phonon spectra is described.
