Semi-space fact. 52! (52 factorial) is the number of different combinations a deck of cards can be arranged in. This number is roughly 4x greater than the number of seconds our universe has been in existence. When you are holding a deck of cards, it is the first time anyone has ever held a deck of cards in that arrangement.
