%N A097345 Numerators of the partial sums of the binomial transform of 1/(n+1).
%C A097345 Numerators in the expansion of log((1-x)/(1-2x)) / (1-x) are 0,1,5,29,.. - _Paul Barry_, Feb 09 2005
%C A097345 Is this identical to A097344? - Aaron Gulliver, Jul 19 2007. The answer turns out to be No - see A134652.
%C A097345 From n=9 on, the putative formula a(n)=A003418(n+1)*sum{k=0..n, (2^(k+1)-1)/(k+1)} is false. The least n for which a(n) is different from A097344(n) is n=59, then they agree again until n=1519. - _M. F. Hasler_, Jan 25 2008
