COMMENTS

Is this a shifted version of A114986 or A096270? - R. J. Mathar, May 16 2011

Response:  A189479(n)=A114986(n-1) for n>=2; this follows from formulas at A099267 (the positions of 1 in A189479) and the fact that A114986 is the characteristic function of the lower Wythoff sequence with 0 prefixed.  - Clark Kimberling, May 22 2011
