A special Math Problem of A New Century's puzzle


Recommended Posts

Please teach me:


I made a new puzzle 5 months ago and found a special

mathematical problem, this problem is still unsolved.


The Puzzle -

consists of eight 3-D connectable cubes

with a solid colour sticker on each of the face of

each cube.


I can twist the layers like twisting the Rubik's cube's layers;


I can shift the layers of the puzzle:

shift the Top layer to be the new Bottom layer,

shift the Right layer to be the new Left layer,

shift the Front layer to be the new Back layer.


I can Overturn the layers of the puzzle:

separate a layer from the Cube Puzzle, turn over this

layer and connect this layer with its opposite side

to the Cube body again.


I knew that there are 8! X 24 ^ 8 = 4438236667576320

different combinations of the 8 cubes, but I don't know

how to calculate the probabilities when we constrain

the manipulations on the Cube, just 3 kinds of

operations are allowed - Twist, Shift, and Overturn.


Is it possible we use just 3 kinds of operations

(Twist / Shift / Overturn) to manipulate the 8 cubes

to form all the combinations ?


How to solve a scrambled such cube puzzle ?


Thank you very much.

The problem is that most of those combinations are just rotations of each other... Each cube has 8 different flavors (determined by the three exposed sides, one for each possible position, everything else is a rotation) and you need to remove all rotations of your initial selection which limits it to 8! * 8! = 1,625,702,400
