Year-end appeal: Please make a donation to the OEIS Foundation to support ongoing development and maintenance of the OEIS. We are now in our 59th year, we have over 358,000 sequences, and we’ve crossed 10,300 citations (which often say “discovered thanks to the OEIS”).

A080605 Golomb's sequence using odd integers. 6

%I

%S 1,3,3,3,5,5,5,7,7,7,9,9,9,9,9,11,11,11,11,11,13,13,13,13,13,15,15,15,

%T 15,15,15,15,17,17,17,17,17,17,17,19,19,19,19,19,19,19,21,21,21,21,21,

%U 21,21,21,21,23,23,23,23,23,23,23,23,23,25,25,25,25,25,25,25,25,25,27

%N Golomb's sequence using odd integers.

%H Ivan Neretin, <a href="/A080605/b080605.txt">Table of n, a(n) for n = 1..10000</a>

%F a(n) = tau^(2-tau)*(2n)^(tau-1)+O(n^(tau-1)/log(n)) where tau is the golden ratio.

%e Read 1,3,3,3,5,5,5,7,7,7,9,9,9,9,9,11,11,11,11,11, as 1,(3,3,3),(5,5,5),(7,7,7),(9,9,9,9,9),(11,11,11,11,11), count occurrences between 2 parentheses, gives 1,3,3,3,5,5,... which is the sequence itself.

%o (PARI) a=[1,3,3,3];for(n=3,20,for(i=1,a[n],a=concat(a,2*n-1)));a

%Y Cf. A001462, A080606, A080607.
