Annual Appeal: Please make a donation to keep the OEIS running. In 2017 we replaced the server with a faster one, added 20000 new sequences, and reached 7000 citations (often saying "discovered thanks to the OEIS").

Table of n, a(n) for n=1..57.

FORMULA

The monotonic ordering of the numbers in the set S generated by these rules:  3 is in S, and if n is in S, then -2+Floor[(n+2)r] and n+Floor[(n+2)r] are in S, where r=(1+sqrt(5))/2, the golden ratio.

MATHEMATICA

nn=200; g=(1+5^(1/2))/2; t={3}; t0=t; While[t=Select[Union[t, -2+Floor[(t+2)g], t+Floor[(t+2)g]], #<=nn&]; t0 !=t, t0=t]; t
