Yep, I did try to do 52 perfect shuffles in a row, live. With, I would say, some success.

This is Peter Rowlett's Aperiodical article "Four perfect hands: An event never seen before (right?)"

Plus Jason Davison did a Numberphile about perfect shuffles and magic.

This is how I actually did the calculation. https://www.wolframalpha.com/input/?i=%2812%21%5E4+39+26+13%29%2F51%21

CORRECTIONS

- The first upload of this video had some serious audio issues. Sorry! It broke when the video was render and because it was only in the middle I didn't spot it once it had uploaded.

- At 07:45 I imply that you might start dealing from the bottom of the deck (obviously I would never dream of such a thing). But the structure is the same as dealing from the top. It was just easier to see from the 'bottom' of the face-up cards.

- 14:01I am inconsistent with "second card in" and "first card in". In both cases I mean the second card along. Which is the first card 'in'.

- Let me know if you spot any mistakes in this version!

Thanks to my Patreon supporters who I used to justify spending several weeks learning how to do a faro shuffle. I'm meant to be writing a new book you know. So, thanks a lot.
