Abstract
Recently Petersen defined a new Mahonian index sor over the symmetric group and proved that and have the same joint distribution. Foata and Han proved that the pairs of set-valued statistics have the same joint distribution over . In this paper we introduce the set-valued statistics and and generalize simultaneously results of Petersen and Foata-Han and find many equidistributed triples of set-valued statistics and quadruples of statistics.
