Über die Inversionsstatistiken von MacMahon und Goulden-Jackson

Abstract. We give a bijection which explains the relation between MacMahon's inversion statistic for multiset permutations and Goulden and Jackson's inversion statistic for permutations with increasing blocks. This provides a simple explanation for MacMahon's combinatorial interpretation of the q-multinomial coefficient.
