COMMENTS

This sequence has a (minimal) period of 328226140474 and a minimal preperiod of 465384263797. The maximal depth is bounded by 15343, so it is sufficient to store (at most) the last 15343+3 values and of course the 15 sparse values and their positions. The last exceptional value is g(465384263796) = 25.  Achim Flammenkamp, May 21 2002
