Kazhdan-Lusztig (KL) polynomials are polynomials in a variable qqq and
with integer coefficients that (for our purposes) are indexed by a pair of permutations [1].
We will write the KL polynomial associated with permutations σ\sigmaσ and ν\nuν as Pσ,ν(q)P_{\sigma,\nu}(q)Pσ,ν(q). For example, the KL polynomial associated with permutations σ=1 4 3 2 7 6 5 10 9 8 11\sigma = 1 ; 4 ; 3 ; 2 ; 7… See the full description on the dataset page:
