FORMULA
a(n) = 1 iff A353486(n) = 3, and 0 otherwise.
a(n) = A059841(n) - A353488(n).
For all n >= 2, a(n) = a(n-2) XOR A353529(n), where XOR is bitwise-XOR, A003987.
PROG
(PARI)
A276086(n) = { my(m=1, p=2); while(n, m *= (p^(n%p)); n = n\p; p = nextprime(1+p)); (m); };
A353489(n) = (3==(A276086(n)%4));
