I am able to solve a 3×3 Rubik’s cube and managed to get somewhere in the 6 minute range for solving it. Over the years, I have seen 4×4 and 5×5 cubes solved by friends, but Kenneth Brandon (AKA RedKB on Youtube) goes even further than that.
Brandon manages to solve a 17×17 Rubik’s cube is a mere 7.5 hours, which is incredible considering that is less time spent than the average American watching TV per week. When it is all said and done there are 66.9 quinquagintatrecentillion (6.69 * 10^1054) possible combinations on this cube. Truly remarkable.
