Edit: "several thousand" could be in the order of millions! (i.e. billions of quadrillions of grains of sand.) Apparently the number of grains of sand per this planet is not so clear. At least to me.
There are more ways to shuffle a deck of cards than there are atoms in the visible universe.
A typical grain of sand contains in the order of hundreds of quadrillions of atoms. A deck of cards can be encoded in 226 bits per deck, so one could encode in the order of a quadrillion decks of cards in a single grain of sand!
What if it's a MtG deck?
There are more ways to configure a single atom than there are card shuffles of a single deck.
what do you mean configure? I guess there are a lot of different electron orbitals but not quadrillions
I could have sworn there were infinite (but as energies increase they become increasingly easy to ionize).
Maybe for some theoretical ideal but definitely not in practice.
