One of the conditions in the main result of the paper [1] is too strict as it stands: Theorem 4.8 should be replaced as follows. Theorem 4.8 Any two triangular tropical matrices X, Y ∈ Un (T) having the same diagonal satisfy the (nontrivial) identities: and w(C,P,n−1) Y w(C,P,n−1) are generated by C and powers P . where w(C,P,n−1) is any word having as its factors all the words of length n − 1 generated by C = { X, Y } of powers P = {1, 2, . . . , n −1}, such that w(C,P,n−1) X w(C,P,n−1) The proof of the theorem appears in [2, Theorem 4.5].
