problem

Let C\mathcal{C} be a cube of side length 2. We color each of the faces of C\mathcal{C} blue, then subdivide it into 23=82^{3}=8 unit cubes. We then randomly rearrange these cubes (possibly with rotation) to form a new 3-dimensional cube. What is the probability that its exterior is still completely blue?

Original LaTeX notation
Let $\mathcal{C}$ be a cube of side length 2. We color each of the faces of $\mathcal{C}$ blue, then subdivide it into $2^{3}=8$ unit cubes. We then randomly rearrange these cubes (possibly with rotation) to form a new 3-dimensional cube. What is the probability that its exterior is still completely blue?
