COMMENTS

a(n) = greatest k such that s(k) = n+1, where s = A026350.
Indices at which blocks (0;1) occur in infinite Fibonacci word; i.e., n such that A005614(n)=0 and A005614(n+1)=1.  Benoit Cloitre, Nov 15 2003
Except for the first term, these are the numbers whose lazy Fibonacci representation (see A095791) includes both 1 and 2; thus this sequence is a subsequence of the lower Wythoff sequence, A000201.  Clark Kimberling, Jun 10 2004; Anumber typo corrected by Nathan Fox, May 03 2014
a(n) = nth number k whose lazy Fibonacci representation (as in A095791) has more summands than that of k1.  Clark Kimberling, Jun 12 2004
a(n) = position of nth 0 in A096270.
