Edit 7: Usually I wouldn't share a method for a trick, However in this case it is a mathmatic sequence, and I haven't seen anyone actually use this method. I'm a bit torn here.. but let's go with it. A version of the concept explained by Brady from Numberphile https://www.youtube.com/watch?v=EWG6e-yBL94 https://www.youtube.com/watch?v=EWG6e-yBL94 Edit 8: Here's some more detail for the math types. Universal cycles for Combinatorial Structures from 1990 by Chung, Diaconis and Graham http://www.math.ucsd.edu/~fan/wp/universalcycle.pdf http://www.math.ucsd.edu/~fan/wp/universalcycle.pdf And Products of Universal Cycles connecting it's application to card tricks by Diaconis and Graham http://www.math.ucsd.edu/~ronspubs/08_05_products.pdf http://www.math.ucsd.edu/~ronspubs/08_05_products.pdf Edit 9: So far I think I've traced this trick back to Charles Jordan in 1919, however given enough time I'm sure there would be better detail.
