C.S. Peirce’s “First Curiosity”: The World’s Most Complicated Card Trick - a paper by Robin Robertson (PDF): http://www.imprint.co.uk/C&HK/vol8/card_trick.pdf

Very interesting.....would like to read about the trick based on the second principle.....

I firstly knew about this trick in Martin Gardner's column in Scientific American and, recently, I discovered the following interesting paper in the American Mathematical Monthly

K. Eisemann. Number-Theoretic Analysis and Extension of ’The Most Complicated and Fantastic Card Trick Ever Invented’.
American Mathematical Monthly, 91:284–289, 1984.

Thanks for the pointer. Sadly enough, I am at the end of the weekend, so its reading will have to wait until next Friday evening.

I have just seen that the paper is just two pages long, so ...

That trick is in the 2nd volume of the collected works of Alex Elmsley, it's caller The Darkest Peirce.

Thanks!!

Thanks Scott, I just came upon this thread. I didn't have a pdf of my article as published myself, so this comes in handy. This was so short because the editor needed a filler in what was to be largely a Peirce issue.

I do have a copy of the pdf of my "Peirce and the Continuum" from the same issue, but that's getting too far afield even for those interested in "Magical Equations."
