Abstract

A Young diagram λ of weight | λ | = n filled by nonrepeating numbers 1, 2,  , n is called a standard filling of shape λ. Given a filling T, we write λ(T) for its shape. Associated with every standard filling T of shape λ = (λ1, λ2, …, λk), ∑ λi = n, are the row subgroup RT ⊂ Sn and the column subgroup CT ⊂ Sn permuting the elements 1, 2,  , n only within the rows and within the columns of T respectively. Thus, \(R_{T} \simeq S_{\lambda _{1}} \times S_{\lambda _{2}} \times \,\cdots \, \times S_{\lambda _{k}}\) and \(C_{T} \simeq S_{\lambda _{1}^{t}} \times S_{\lambda _{2}^{t}} \times \,\cdots \, \times S_{\lambda _{m}^{t}}\), whereλt = (λ1t, λ2t, …, λmt) is the transposed Young diagram. For example, the standard filling
