On the index, I link to a PDF written by Brad Mann from Harvard that studies
the Riffle Shuffle, which includes the birthday paradox and Markov chains. I
could certainly create a page that summarized the highlights in that PDF, and
what it takes to introduce sufficient unpredictability into a standard deck
using the Riffle Shuffle. I think there are other pages that could be created,
minimizing the amount of content that needs to be digested on each page.
