%N Total number of partitions of all positive integers <= n into an odd number of consecutive parts.
%C a(n) is also the total number of odd divisors of k less than sqrt(2*k), for k = 1..n.
%C Conjecture: a(n) is also the total number of subparts present (totally or partially) in an octant of the symmetric representations of sigma of all positive integers <= n.
%C For more information about the "subparts" of the symmetric representation of sigma see A279387 and A237593.
%F a(n) = A060831(n) - A285902(n).
%Y Partial sums of A082647.
