I looked in the Rotations section of the Workout Manager and see at least two versions, one under each column heading. You might also try doing a word search on the STS forum, as it has been talked about quite a bit. I don't have it handy or I would be glad to share it with you.
ETA: Sorry. I just read that you were asking for Cathe's version of the undulating rotation and I was pointing out Cathlete versions.
