Hi Yefim,

Are you sure that 3! = 9?

         Hello from Yefim. 
  Have in mind that for many positions a set of SPG is much more than 1. The following simple examples you may use for instructional purposes (and please check my solutions).
  How many SPG exist for the following positions with my answers:
  rnbqkbnr/pppp1ppp/8/4p3/4P3/8/PPPP1PPP/RNBQKBNR w KQkq
  Answer is: 1!=1;
  rnbqkbnr/ppp2ppp/8/3pp3/3PP3/8/PPP2PPP/RNBQKBNR w KQkq 
  Answer is (2!)^2=4;
  rnbqkbnr/ppp3pp/8/3ppp2/3PPP2/8/PPP3PP/RNBQKBNR w KQkq 
  (3!)^2=81;
  ...
  rnbqkbnr/8/8/pppppppp/PPPPPPPP/8/8/RNBQKBNR w KQkq
  Answer is (8!)^2=1625702400;
  I hope, you understood the idea and now a funny example for you to solve.
  rnbqkbnr/ppp2ppp/4p3/4P3/3p4/3P4/PPP2PPP/RNBQKBNR w KQkq 
  How many SPG for this?
