The Rook polynomial is a combinatorial polynomial used in the study of permutations and combinatorial objects on a chessboard-like grid, specifically related to the placement of rooks on a chessboard. The Rook polynomial encodes information about the number of ways to place a certain number of non-attacking rooks on a chessboard of specified dimensions.
