Studying the Sigma-reducibility of families introduced by [Kalimullin and Puzarenko 2009] we show that for every set X >=(T) empty set' there is a family of sets F which is the Sigma-least countable family whose Sigma-jump is Sigma-equivalent to X circle plus (X) over bar. This fact will be generalized for the class of n-families (families of families of ... of sets).
