A good example of a random permutation is the shuffling of a deck of cards: this is ideally a random permutation of the 52 cards.

Batch shufflers are more expensive, but can avoid the problems associated with some continuous shufflers, whereby the shuffling operation only slowly changes the state of the deck, and new cards may be taken before shuffling has sufficiently randomized the pack, allowing some players to " shuffle track " cards through the shuffling process.

The two packs would be placed upon each other to form a new deck and the operation could be repeated for better shuffling.
