Abstract
The rook polynomial of a board counts the number of ways of placing non attacking rooks on the board .In this paper; we classify all possible cubic polynomials that are the rook polynomial for some generalized board B under certain conditions. Here we prove theorems regarding rook equivalency which allow us to minimize the number and type of boards that we need to work with for enumerating all possible cubic rook polynomials.
Keywords: Rook numbers, generalized board, rook polynomial
