 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"). Other ways to donate

 OFFSET 1 COMMENTS This is column 3 of the array A188294. This sequence is essentially the same as A188011. - Michel Dekking, Oct 03 2016 LINKS FORMULA a(n) = [3r]-[nr]-[3r-nr], where r=(1+sqrt(5))/2. a(n) = 1-A188011(n) for all n>0, except for n= 3 (from [-x]=-[x]-1 for non-integer x). - Michel Dekking, Oct 03 2016 MATHEMATICA r = (1 + 5^(1/2))/2 + .0000000000001; f[n_] := Floor[3r] - Floor[n*r] - Floor[3r - n*r] t = Flatten[Table[f[n], {n, 1, 200}]] (* A188436 *) Flatten[Position[t, 0] ]  (* A188437 *) Flatten[Position[t, 1] ]  (* A188438 *) CROSSREFS Cf.
