COMMENTS

Conjecture: -1 < n*r - a(n) < 1 for n>=1, where r = 1 + sqrt(1/2).

This conjecture can be proved in the same way as the conjecture on A285074. - Michel Dekking, May 30 2017

Appears to differ from A285074 only at a(1). - R. J. Mathar, Apr 24 2017

This is correct, and follows from the fact that A285073 and A285076 are equal except for the first two terms which are respectively 0,1 and 1,0. (See Comments for A285073.) - Michel Dekking, May 30 2017
