If moving 1 piece pushes/moves N-1 other pieces, does that count as 1 move or N moves?

Neil is tabulating the "hardest" 4x4s according to polyomino size histogram. Some of the short ones are tricky. E.g., a four-piecer: http://gosper.org/4x4-3,0,0,1,0,0,0,0,0,0,0,0,0,0,0,0.gif . Five moves to get the tetromino to the lower right, where a move is of one piece along any path. --rwg _______________________________________________ math-fun mailing list math-fun@mailman.xmission.com http://mailman.xmission.com/cgi-bin/mailman/listinfo/math-fun
