A standard deck of 52 unique cards can be arranged in 52! (52 factorial) different orders.

That's:80,658,175,170,943,878,571,660,636,856,403,766,975,289,505,440,883,277,824,000,000,000,000

Or roughly 8.0658 × 10⁶⁷

False. Yes it's improbable to get the exact same shuffle, but it could happen being as a fresh pack of cards is always the same order. One shuffle would be significantly higher odds. 3 shuffles, a cut, and a shuffle... Well I'm no mathemagician.

Still, it would be a pretty good magic trick to go over the odds and shuffle two decks to the same order.

Yes this is the common caveat. The logic assumes the deck has already been shuffled.
