It is shown that the problem of spin-density-wave formation in a quasi-one-dimensional organic conductor (TMTSF(Formula presented)(Formula presented) in a magnetic field is equivalent to Brazovskii-Dzyaloshinskii-Kirova variant of an exactly solvable one-dimensional problem of Su-Schrieffer-Heeger (SSH) solitons. We demonstrate that the ground state in (TMTSF(Formula presented)(Formula presented) in high magnetic fields corresponds to SSH solitonic superstructure. We calculate the magnetic moment and energy gap in an electron spectrum and discuss recent experimental data in terms of the creation of SSH solitonic superstructure.
