My friend always insists on scrambling my Rubik's cube "perfectly" before giving it to me to solve. According to his definition, a "perfect" scramble must have no three of the same color touching (which takes an annoyingly long time to achieve). For example, this scramble is not a perfect one (showing the front face only):
RRG BRB YWO
because three red squares are touching, while this one is perfect:
RRG BBR YWO
Is it possible to achieve a scramble where no two same-colored squares are touching, on all sides?
