AbstractIn this paper we study permutations of the multiset {1r, 2r, …, nr}, which generalizes Gessel and Stanley's work (J. Combin. Theory Ser. A24 (1978), 24–33) on certain permutations on the multiset {12, 22, …, n2}. Various formulas counting the permutations by inversions, descents, left-right minima, and major index are derived
