Cubic Impression (Posted on 2013-11-02) Difficulty: 3 of 5
Express each of X, Y and Z in terms of a,b,c,p,q and r so that the equation given below becomes an identity.

(a3+b3+c3 - 3abc)(p3+q3+r3 - 3pqr) = X3+Y3+Z3 - 3XYZ

Note: Disregard any permutations. For example, if (X, Y, Z) = (α, β, γ), then (X, Y, Z) = (β, γ, α) is invalid.
