Abstract

By definition the identities [x1,x2]+[x2,x1]=0[x_1,x_2]+[x_2,x_1]=0 and [x1,x2,x3]+[x2,x3,x1]+[x3,x1,x2]=0[x_1,x_2,x_3]+[x_2,x_3,x_1]+[x_3,x_1,x_2]=0 hold in any Lie algebra. It is easy to check that the identity [x1,x2,x3,x4]+[x2,x1,x4,x3]+[x3,x4,x1,x2]+[x4,x3,x2,x1]=0[x_1,x_2,x_3,x_4]+[x_2,x_1,x_4,x_3]+[x_3,x_4,x_1,x_2]+[x_4,x_3,x_2,x_1] = 0 holds in any Lie algebra as well. We investigate sets of permutations that give identities of this kind. In particular, we construct a family of such subsets Tk,l,nT_{k,l,n} of the symmetric group Sn,S_n, and hence, a family of identities that hold in any Lie algebra.
