Looks like you're going to have to find a copy of "Lecture notes in mathematics" --
Springer-Verlag, Germany(1979) to find out their proposed algorithm (or one of Foulds' other books, and he seems to have a few), but I found a text description of it
here, pg. 4, and a subsequent discussion on the "Deltahedron Method"
here, which does give an algorithm, but doesn't necessarily describe it as Foulds'.
Hope that helps,
C-.
Update: After reading the Caccetta/Kusumah text, theirs might be a more interesting algorithm to attempt implementing if you are going to start from scratch.
