 OFFSET 1 COMMENTS See A188294.  First differs from A078588 at the 38th term. (a(n)) is essentially the same as A188014 and also as A187950. The second sequence is a shift of (a(n)), and the first sequence is obtained by applying [-x]=[x]-1 for all non-integer x. This gives a(n) = 1-A188014(n) for all n not equal to 4. - Michel Dekking, Oct 04 2016 LINKS FORMULA a(n)=[4r]-[nr]-[4r-nr], where r=(1+sqrt(5))/2.
