Abstract
We prove that the isotopes of the alternative monster and the Skosyrsky algebra satisfy the identity П 4 i=1 [x i , y i ] = 0. Hence, the algebras themselves satisfy the identity П 4 i=1 (c, x i , y i ) = 0. We also show that none of the identities П n i=1 (c, x i , y i ) = 0 holds in all commutative alternative nil-algebras of index 3. Thus, we refute the Grishkov–Shestakov hypothesis about the structure of the free finitely generated commutative alternative nil-algebras of index 3.
