In some 1D conductors such as orthorhomic TaS3 and vanadium bronze, the energy band is one-quarter filled. Due to the instability of 1D lattice caused by the electron-lattice interaction, there appears quadrimerization in the lattice, and the ground state becomes four-fold degenerate with different
