%F a(n) = A329697(n) * A334204(n) = A329697(n) * A329697(A163511(n)).

%o (PARI) A334873(n) = (A329697(n) * A334204(n));

%Y Cf. A163511, A329697, A334204, A334867.

%Y Cf. A000079 (positions of zeros); It is also conjectured that A007283 gives the positions of ones, and that A070875 gives the indices of twos.
