The nine squares of a 3-by-3 chessboard are to be colored red and blue. The chessboard is free to rotate but cannot be flipped over. Determine the generating function for the number of nonequivalent colorings and the total number of nonequivalent colorings.
Added by Rebecca K.
Step 1
Since the chessboard can be rotated but not flipped over, we can use Burnside's Lemma to calculate the number of nonequivalent colorings. Show more…

Consider a 1-by-n chessboard. Suppose we color each square of the chessboard with one of the four colors: red, yellow, green, and blue. Let hn be the number of colorings in which the number of squares colored red is even and the number of squares colored blue is odd. Find the generating function for the sequence hn and then find a formula for hn.
