Equally, a(n) = 1 if A349905(n) == 3 (mod 4), otherwise 0.
FORMULA
a(n) = [A349905(n) == 3 (mod 4)], where [ ] is the Iverson bracket.
a(n) = A066829(n) - A358751(n).
a(n) = A358773(A003961(n)).
For all n >= 1, a(n) >= A101605(n).
PROG
(PARI) A358753(n) = (3==(bigomega(n)%4));
CROSSREFS
Characteristic function of A358763.
Differs from A101605 for the first time at n=128, where a(128) = 1, while A101605(128) = 0.
