I just realize that I answered the wrong question! My answer was to the
"My cube is completely solved *except* that the 2 pieces marked `O' are
(Sorry.) The right answer should be:
The state of the cube is not:
X|O|X|X|X X|A|X|C|X X|X|X|X|X X|X|X|X|X X|X|X|X|X But rather: X|X|X|X|X X|X|X|X|X X|X|X|X|X X|X|X|O|X X|X|X|B|X
Where cubie "C" just "looks" like it's in the right place.
You need an operator that rotates A->B->C->A. (Left as an exercise; hints
available on request.)
This will very likely leave an inconvenient number of edges flipped. For
the answer to _this_ problem, see my last post. ;)
