My object was to create a unique 4 digit square number on each face. At the same time I required each vertex to be a 3 digit square. I failed in that objective!

I have 6 unique 4 digit squares but I have duplicated just one of my vertices.

To emulate my "feat":

- a [Magenta]

**Magenta**cell is both the first digit of a 3 and 4 digit square

- an [Orange]

**Orange**cell signifies the first digit of only a 4 digit square, while

- a [Cyan]

**Cyan**cell signifies the first cell only of a 3 digit square.

The digits must be applied to each face by rotation, the direction is defined by need. "A" through "F" represent the 6 faces of the cube while "a" through "h" represent the vertices of the cube when fully assembled.

**Within the range allowed several squares utilise the same digits, and this is allowed by virtue of the commencement cell.**

__Note:__But then, there is still the challenge for 6 unique faces and 8 unique vertices.
