FORMULA
a(n) = A126760(n) - A347233(n).
a(n) = Sum_{d|n, d<n} A347233(d).
a(n) = -Sum_{d|n, d<n} A008683(n/d)*A126760(d).
PROG
(PARI)
A126760(n) = {n&&n\=3^valuation(n, 3)<<valuation(n, 2); n%3+n\6*2}; \\ From A126760.
A347233(n) = sumdiv(n, d, moebius(n/d)*A126760(d));
A359165(n) = (A126760(n)-A347233(n));
