COMMENTS

a(n) modulo 2 is the ProuhetThueMorse sequence A010060.
The sequence of Jacobsthal numbers A001045 begins [1, 1, 3, 5, 11, 21, ...] with two occurrences of the term 1. Allowing for this, we find that the numbers representable as a sum of distinct Jacobsthal numbers form A050292.  Peter Bala, Feb 02 2013
Partial sums of A056832.  Reinhard Zumkeller, Jul 29 2014
