Minh Thai wrote a booklet entitled "The Winning Solution to Rubik's
Revenge" that was published in 1982.  I never went though his method,
but I noticed he counted the number of positions wrong by a factor of
two.  Anyway, it's out of print now.

At any rate, it's easy, if laborious, to solve it using commutators.
See J. A. Eidswick's article in the March, 1986 American Math Monthly.
