Our physical model consists of an inner binary system, which in turn consists of two southern components S1 and S2, and an outer binary system, which consists of a southern component S1+S2 and a northern component N. The distance between S1 and S2 is 198 pc, and between S1+S2 and N 856 pc. Thus, according to the obtained results, the connected system S1 and S2 was formed in ~3 million years. The formation of a hierarchical ternary system occurs  in ~18 million years, but not for all sets of randomizations. Also, the von Zeipel-Lidov-Kozai effect was found for most of the models.
