Abstract: By analyzing the properties of the basis of k-polynomial algebra generated by n elements over their invariant subring,  and dividing  the symmetric group with n letters, we obtained the discriminant of polynomial algebra generated by four elements.

Key words: discriminant, polynomial algebra, invariant subring, basis, symmetric group
