In its solved state all colors and numbers only represented once per face.

A virtual model of this cube can be found on this page:

A total of 21 additional solutions (apart from the initial state of the cube) have been found so far.

But we are convinced that there are many more ... so therefore, our question is how many?

It has proved to be very difficult to understand the cube on a more fundamental level and thus to get a full picture of the possibilities inherent in it.

We would be very interested to know if you can find additional valid solutions ... or even all of them.

The following images are showing the frontside and backside of all known 8 Color Cube solutions.
