Concerning the Saturday puzzle of http://list.seqfan.eu/pipermail/seqfan/2010-March/003860.html :

ftaw> There is a Mathematica program in A103969, so it must be computing 
ftaw> something.  I can't really tell what, from a quick examination.  Is 
ftaw> this just a buggy program and a sequence that should  not be present, 
ftaw> or is it something of some possible interest?

I think the sequence A103969 shows "n such that A005941(n)=A005940(n),"
a kind of "positions of fixed points", correlated with A029747 .
This speculation is at least correct up to 64 = A103969(23).
