A deck of 52 cards can be arranged in more ways than there are atoms on Earth. This is a record of the search.
The archive, as dust
This is one shuffle.
One ordering of 52 cards, out of 8.07 × 10⁶⁷ possible.
The whole archive, as dust.
Every speck is 200 shuffles. 16,357,903 recorded so far. Zero matches.
Zoom out. The archive vanishes.
Humanity has dealt at most 10²⁰ shuffles in a thousand years of card games. Against that, this whole field shrinks toward a speck. And 10²⁰ is nothing at all against 52!.
There is no screen big enough.
Showing every possible deck at one per pixel would take a display millions of times larger than the cross-section of the observable universe.
Still searching.
Everything recorded here is a speck in that dark. The next one could be yours.
The Math
8.07 × 10⁶⁷
Possible arrangements of a 52-card deck.
More than atoms on Earth, and by 100 quadrillion times. Earth has roughly 10⁵⁰ atoms. Every shuffle you've ever done by hand has never existed before, and never will again.
10²⁰
Total shuffles by all humans in history.
That's the estimated upper bound: every card game, every casino, every kitchen table. Against 8.07 × 10⁶⁷ possibilities, it doesn't register.
8.7 × 10³³
Shuffles if every ant on Earth went for the age of the universe.
~20 quadrillion ants × 4.35 × 10¹⁷ seconds. You'd need to run that scenario 9 nonillion times to exhaust every arrangement.
2.5 × 10⁶⁰
Years to see every arrangement at one per second.
The universe is 13.8 billion years old. You have some time.
12,300,339

That covers roughly 0.000000000000000000000000000000000000000000000000000000000015% of all possibilities. (59 decimal places. Count them.)
