There is a variant of the classic rubik's cube called the V-Cube 7 which, instead of being three cubes to a side, is seven by seven by seven - hence the name. If you considered it a solid block of cubes, that would make a total of 343 cubes. As you know, these cubes are not solid, and can in fact rotate and transform into mind bogglingly complex permutations. The V-Cube 7 has... take a deep breath... 19.5 duoquinquagintillion different arrangements of tiny, brightly colored squares.
Right now you're probably saying, "But wait, Mr. or Mrs. Wellesley High School Librarian, I'm familiar with millions, billions, and trillions, but after quad- or quintillions things get a little fuzzy. Can't we just use scientific notation?"
We sure can! 19.5 duoquinquagintillion can be shortened to 19.5 x 10^160. That's a hundred and sixty zeros. Ok, technically one hundred and fifty nine, since one of those will actually be the five from the original number. Actually, this is just a rough estimate, to make it a little easier to explain the size of this absurd number. If you actually cared to calculate and write out every since digit it would be:19,500,551,183,731,307,835,329,126,754,019,748,794,904,992,692,043,434,567,152,132,912,323,232,706,135,469,180,065,278,712,755,853,360,682,328,551,719,137,311,299,993,600,000,000,000,000,000,000,000,000,000,000,000Holy$*%&ItWentOffThePage!
That's more atoms than there are in the observable universe.
