Points P and Q are given by position vectors OP = i - j - k and OQ = -i + j + k. A line along the vector a = i + j passes through P and another line along the vector b = j - k passes through Q. If a line along the vector c = i - j + k intersects both lines at L and M respectively, then the vector PM is:
