Symmetry of the large system and decoupling of its mathematical model

Methods investigated in this paper allow us to transform the set of equation to some independent subsystems or to state that such decomposition is impossible.
At the first step we use a priori information about symmetry of the proper system. Then algebraic methods are used. The way of the composition of symmetry group corresponding to the found decoupling is considered.
