  10. for the bishop problem, you say that (for example) there are 64-8=56 safe
  11. places to put the second bishop.  however, this is not true.  consider the
  12. case, for example, when the first bishop is placed in one of the four
  13. center squares of the board.  the second bishop then is not safe in fifteen,
  14. not eight, places.
