Imagine you're trying to find a single specific grain of sand on all the beaches on Earth. There are about 2^62 to 2^63
grains of sand on all beaches combined. Puzzle 71 is like trying to find not just one grain, but a Puzzle 71 (2^70) = 157.4x Earth's sand. Even if you could check a billion grains every second, it would take you thousands of years to go through them all.
