A world first!
52 shriek
The chances that anyone has ever shuffled a pack of cards in the same way twice in the history of the world are infinitesimally small, statistically
speaking. The number of possible permutations of 52 cards is ‘52 factorial’ otherwise known as 52! or 52 shriek. This is 52 times 51 times 50 . . .
all the way down to one. Here's what that looks like:
80,658,175,170,943,878,571,660,636,856,403,766,
975,289,505,440,883,277,824,000,000,000,000.
