    • 1 includes the small contribution from cyclic exchange. We have shown that the other bilinear terms produced by cyclic exchange have negligible effects.

    • In that case, the solution is unique and the sign of the bulk dimerization is fixed by the local condition of maximum overlap between the two solitonic clouds.

    • Two equivalent symmetric solutions are obtained with opposite signs of the bulk dimerization.
