We consider quotients of the unit cube semigroup algebra by particular Zr≀Sn-invariant ideals. Using Gröbner basis methods, we show that the resulting graded quotient algebra has a basis where each element is indexed by colored permutations (π,ϵ)∈Zr≀Sn and each element encodes the negative descent and negative major index statistics on (π,ϵ). This gives an algebraic interpretation of these statistics that was previously unknown. This basis of the Zr≀Sn-quotients allows us to recover certain combinatorial identities involving Euler–Mahonian distributions of statistics. |
