43 Quintillion permutations too easy?
The standard 3x3x3 Rubik’s Cube has a lot of permutations (43,252,003,274,489,856,000 to be exact), but that’s not challenging enough for some. One person decided to solve a 17x17x17 cube, designed by puzzle designer Oskar van Deventer (http://goo.gl/uhMwV3
), which has 6.69 x 10^1054 permutations. That’s a lot of zeros!
