And btw, you math nerds, got one for this?

What's also cool about them...even with that many combinations, you're never more than ~20 steps away from solving it. And that's worst-case; many are even less.

Like was said, it's all just an algorithm. Pretty cool video on why we've likely achieved the best possible world-record solving time:

I printed out instructions for solving my 3x3 after the kids mess it up. I don't know why they play with it anyway, it's not a freakin toy

True, but that's cheating.

I can solve one until the last step, I don't have those algorithms memorized yet. Of course, that's the hardest part with a bunch of different steps depending on how it ended up from the first and middle steps.

On a 13 sided cube there are 11 per edge on a 6 sided cube that can be positioned 2 ways making the numerator 33?

8x3^8332^33/3x2x2

I really feel like holding the cube in my hand to physically count and examine the movements would help. Trying to imagine the individual blocks in a mental depiction is less than ideal. Fun trying to work through this though.
Main thing to keep in mind is that many configurations are not possible. For example, if you take one edge piece, pull it out, reverse it, and put it back in, the cube is now unsolvable.

Something with the same mathematical ideas that's much more basic is the classic "15-puzzle". It also has it's own crazy history and lore:

Yep, im great at maths and stuff but i dont even understand the concept of the rubiks cube. I guess i havent really put any thought into it either.

The first time I saw someone speedsolve it in the 1980s I lost interest.

You should look at how many unique combinations you can get from a deck of cards.

Pretty vague statement...

Do you mean all possible orderings of the 52 cards? That's easy: 52!.

EDIT: But yeah, it is a huge number.

Same here but a couple months ago I saw one on the shelf at target and figured I'd buy it and give it a shot. Tried for a few days on my own then started researching it.

There are actually multiple ways to solve them. First is to do it in order starting with the white cross, then the corners, then the sides in order, then the yellows. The yellow corners are the hardest part, getting them in order without fucking up the sides. Different algorithms for each step, with a couple common moves to get pieces into the right position.

Another way to do it is from a random scramble, and there are a couple algorithms to do it without going through the previous process. I don't know those ones.

Holy shit. Yeah, that's a huge number, and another one that I cannot comprehend. Mind blown again.

Apparently it's more than there is atoms making up the earth, and it's "almost certain that the shuffled deck of cards you're holding in your hand has never been duplicated and never will be duplicated, ever"

I should start a booth at a carnival where for ten bucks you can take three tries to shuffle a deck of cards to match the deck of cards that I'd be holding. Payout would be a million dollars.

Yeah, it is pretty incomprehensible, given the odds of winning the powerball jackpot are "only" 1 in 292,201,338.
