The Rubik’s Cube – one of the world’s best selling toys – is a 3D puzzle that was invented by Hungarian professor of architecture Ernő Rubik in 1974.
There are 43,252,003,274,489,856,000 possible arrangements of the cube!
🔵 Some interesting facts:
📌 43 quintillions is a number so large that you could easily come up with an arrangement that no human has ever achieved before.
📌 Getting from any of the 43,252,003,274,489,856,000 arrangements to any other of the 43,252,003,274,489,856,000 arrangements can be done in only 31 moves.
📌 And from any one of those 43,252,003,274,489,856,000 starting positions, the cube can be solved in ≤20 moves — as proven in 2010 (1).
