Tracing Card Paths during Perfect Shuffles
Tracing Card Paths during Perfect Shuffles
This Demonstration displays the path that each card takes through a deck over the course of a sequence of consecutive perfect shuffles. Each colored line traces the path of one card as a plot of position versus time. Use the controls to adjust the number of cards in the deck and whether the shuffle is an in-shuffle or an out-shuffle. The minimum number of shuffles required to return the deck to its original order is shown at the top.
