Two-body and three-body substructures served as building blocks in small   spin-3 condensates
  It was found that stable few-body spin-structures, pairs and triplexes, may exist as basic constituents in small spin-3 condensates, and they will play the role as building blocks when the parameters of interaction are appropriate. Specific method is designed to find out these constituents.
