The Rubik’s Cube – one of the world’s best selling toys – is a 3D puzzle that was invented by Hungarian professor of architecture ErnΕ‘ Rubik in 1974.

There are 43,252,003,274,489,856,000 possible arrangements of the cube!

πŸ”΅ Some interesting facts:

πŸ“Œ 43 quintillions is a number so large that you could easily come up with an arrangement that no human has ever achieved before.

πŸ“Œ 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.

πŸ“Œ And from any one of those 43,252,003,274,489,856,000 starting positions, the cube can be solved in ≀20 moves β€” as proven in 2010 (1).
