Examples of minimal (up to the number of elements) systems of generators are described for normal subgroups of hyperoctaedral groups. The algorithm of construction of the systems of generators for wreath product of two alternating goups is given, and the specific systems of generators, which consists of only two elements, are described. The properties of associative algebra R, which are close to the sums of their nilpotent subalgebras, in particular those that are two nilpotent subalgebras A and B are so that their sum A+B (as vector subspaces) has a finite codimension in algebra R. The results about properties of groups and theoretic-groups of structure for triangular and unitreangular automorphisms of the polynomium rings from two variables above the fields. Groups of three-corner automorphisms are investigated for zero-characteristic fields, and groups of untricut automorphisms are used for fields of both zero characteristics and characteristics, including finite fields. The peculiarities of development of general mathematical training in educational institutions of Chernivtsi region and mathematical education and science in Chernivtsi University during the stay of the region in the Ukrainian SSR (1940-1941, 1944-1991) were revealed.
