OK... in how many ways can White's pawns be arranged on a chess board, in such a way that they could have got there in a game of chess?

OK. Place 20(twenty ) queen pieces on a chessboard such that each one attacks ( and is attacked by) just four others on the chessboard.
Try to get this. If you haven't seen it's solution from somewhere on the net, then you won't be able to solve it in one sitting. Challenge yourself on this and see how much time do you take in your first ever attempt.
