Askar Dzhumadil'daevN-commutators and identitiesA commutator $[X,Y]=XY-YX$ is a well-known tensor operation on a space of vector fields $Vect(n).$ We construct new tensor operation on $Vect(n).$ Namely, we establish that $N$-ary skew-symmetric sum of $N$ compositions by all permutations is a well-defined operation if $N=n^2+2n-2.$ References. 1.A.S.
