%N a(n) = A353460(n) + A353461(n).

%C The first negative term is a(935) = -8.

%F a(n) = A353460(n) + A353461(n).

%F For n > 1, a(n) = -Sum_{d|n, 1<d<n} A353460(d) * A353461(n/d). [As the sequences are Dirichlet inverses of each other]

%o (PARI) A353462(n) = (A353460(n) + A353461(n));

%Y Cf. A353460, A353461.
