A standard Rubik’s Cube is 3 x 3 x 3. According to Wikipedia, there exist 519 quintillion permutations for positioning. The world’s largest Rubik’s Cube is 17 x 17 x 17, has squares of varying sizes and, according to The Verge, there exist 66.9 quinquagintatrecentillion permutations.
YouTube user RedKB solved it in seven hours (or, rather, seven hours and five days of prep work). You can also see the entire un-lapsed seven-hour video at his channel.
This simultaneously fascinated me and gave me a panic attack because there are Rubik’s Cube brains and there are brains who do not work this way. Mine does not work this way. My husband gives IQ tests for neurological assessments as part of his job and tested me. During the block design test portion, I just broke down screaming, “I DON’T KNOW WHAT YOU’RE ASKING ME TO DO,” and got hives, so this video took me back to a bad place. I think I need to watch some puppy videos to feel better, maybe a newly svelte dachshund or something.
Anyway. Great job, RedKB. See you when someone invents a 30 x 30 x 30. And just thinking of that brought back the hives.
