My friend has been working on mastering the Rubik's cube lately. He can solve it now and make new designs. One day he asked me for a pattern so, I told him I wanted the red center piece enclosed by the green cubes, and the green center piece enclosed by the red cubes. I think this is impossible, but he beleive it is. Does anyone know if this can be done? The Cube looks like this: Placing the cube flat on a cube, the color of the face facing me is red. Moving right the colors are blue, orange and green and then back to red. The face at the bottom is yellow and the face on top is white.
