Cards lifted after a riffle shuffle, forming what is called a bridge which puts the cards back into place After a riffle shuffle, the cards cascade. A common shuffling technique is called the riffle, or dovetail shuffle or leafing the cards, in which half of the deck is held in each hand with the thumbs inward, then cards are released by the thumbs so that they fall to the table interleaved.
A faro shuffle that leaves the original top card at the top and the original bottom card at the bottom is known as an out-shuffle, while one that moves the original top card to second and the original bottom card to second from the bottom is known as an in-shuffle. These names were coined by the magician and computer programmer Alex Elmsley. [6]
DNA shuffling has since been applied to generate libraries of hybrid or chimeric genes and has inspired family shuffling which is defined as the use of related genes in DNA shuffling. [17] [18] [19] Additionally, DNA shuffling has been applied to protein and small molecule pharmaceuticals, bioremediation, gene therapy, vaccines, and evolved ...

Diaconis received a MacArthur Fellowship in 1982. In 1990, he published (with Dave Bayer) a paper entitled "Trailing the Dovetail Shuffle to Its Lair" [11] (a term coined by magician Charles Jordan in the early 1900s) which established rigorous results on how many times a deck of playing cards must be riffle shuffled before it can be considered random according to the mathematical measure ...
Shuffle algebra, a Hopf algebra with a basis corresponding to words on some set whose product is given by the shuffle product XшY of two words X, Y: the sum of all ways of interlacing them; Shuffle product, the shuffle product of words of lengths m and n is a sum over the (m+n)!/m!n! ways of interleaving the two words
In the mathematics of permutations and the study of shuffling playing cards, a riffle shuffle permutation is one of the permutations of a set of items that can be obtained by a single riffle shuffle, in which a sorted deck of cards is cut into two packets and then the two packets are interleaved (e.g. by moving cards one at a time from the bottom of one or the other of the packets to the top ...
