(4! 6)) 2. The position of its 24 outer side blocks cannot be moved at will, so there are 24 in total! A state of change. Eleven of the 12 central edge blocks can be swapped, so there's a total of 12! Over 2 times 211 different states. Five order rubik's cube change state of the total number is 282870942277741856536180333107150328293127731985672134721536000000000000000.
