It is well known that for some groups this problem is an extremely difficult problem. The unitriangular group is one of these groups. For this group, C. Andre proposed the theory of basic characters. These characters are not irreducible, but have a lot in common. One of the results of this theory is that a basic character is a product of elementary characters. In this paper, we obtain the similar result for supercharacters of the triangular group.</p>теория суперхарактеровсуперклассытреугольная группаupercharacter theorysuperclassestriangular group
