    • n rook A kind of crow, Corvus frugilegus, abundant in Europe. It is entirely black, with the parts about the base of the bill more or less bare of feathers in the adult. The size is nearly or about that of the common crow; it is thus much smaller than the raven, and larger than the jackdaw. It is of a gregarious and sociable disposition, preferring to nest in rookeries about buildings, and feeding on insects and grain.

The Matrix Ansatz, Orthogonal Polynomials, and Permutations
In Section 2, we recall some elementary facts concerning moments of orthogonal polynomials, and explain how the Matrix Ansatz sheds new light on some known examples, e.g. the connection between rook placements and Hermite polynomials.
The Matrix Ansatz, Orthogonal Polynomials, and Permutations
It’s easy to see that hW |X |V i enumerates rook placements in Young diagrams of “shape” X , where • there is exactly one rook per row, • a counts the columns without rook, • q counts each cell with no rook to its right in the same row, nor below it in the same column.
The Matrix Ansatz, Orthogonal Polynomials, and Permutations
And then since the moments µh n of the continuous big q -Hermite polynomials are given by hW |(F + U )n |V i, we recover results of [Var05]: µh n enumerates such rook placements in all Young diagrams where the number of rows plus the number of columns is n.
