... transposingtheentries 0and1 atindices 1and2 of(µ + α)[ ] or by transposing the entries −2 and −3 at indices 3 and 4. The result can be written as (4, 3, 3, 2, 2)[ ] respectivelyas (4, 2, 4, 1, 3)[ ], and indeed ... Corollary. For λ, µ ∈Pand α ∈C, the Kostka number Kλ/µ,αequals thenumber # SST(λ/µ, α) of semistandard tableaux of shape λ/µ and weight α ,and Kλ/µ,αis the number of transposed semistandard tableaux ... down columns, and for thisreason semistandard tableaux are also called column-strict tableaux (and transposesemistandard tableaux are then called row-strict tableaux).
