Here’s a Fun math fact:
There are 1 billion trillion stars in the sky. That’s 10 times more than there are grains of sand in the whole planet
BUT
There are even more ways than that to shuffle a single deck of cards, which is 52 factorial.
80 unvigintillion, 658 vigintillion, 175 novemdecillion, 170 octodecillion, 943 septendecillion, 878 sexdecillion, 571 quindecillon, 660 qauttuordeciallion, 636 tredecillion, 856 duodecillion, 403 undecillion, 766 decillion, 975 nonillion, 289 octillion, 505 septillion, 440 sextillion, 883 quintillion, 277 quadrillion, 824 trillion
Or roughly 8 * 10^67
