I'm back from my trip, but it will be a few days before
I get caught up.   Three new "unkown" sequences came
in while I was away, and I append a fourth from earlier in the month.
Let me know if you solve any of them.  
Of course I do not know the answers, or I would have included
the definitions.

%C A100696 One can check that the terms shown all belong to A006037 (Weird numbers), but the additional property needed to pick out just these numbers is not obvious. - Max Alekseyev (maxal(AT)cs.ucsd.edu), Mar 28 2006
