Funny you should mention that. Dr. Richard V. Andree here at the
University of Oklahoma came up with it one fine day to give a student
an example of a recurrence relation, and discovered that it was *far*
more interesting than it at first appeared. I recall hearing that every
starting value up to 10**40 either terminates or loops. A book by
Nievergelt et al., I think called *Computer-Assisted Problem Solving*,
gives further analysis of this recurrence relation.
