... for m<n, one can obviously place at most m nonattacking queens and for 4 m<n,one can just take a solution on the m ì m board and extend the board. Moreover, the reader will easily nd solutions on ... reader will readily find that there is no solution on the 6 ì 3 board, but there are solutions on the 9 ì 3 board. It follows that there are solutions on the n ì m board for all m&...
