Don, Those notes are very nice! I have been doing essentially the same
thing, although you are way ahead of me. Will try to catch up.
Michael Branicky has also been looking at the sequence. Earlier today he
sent me an email saying:

5 does not appear in the first 3.33 billion terms.

My present guess is that 5 will eventually appear. But my opinion may
change after I've digested your notes.
