%N Records in A192013: Sum_{d|n} Kronecker(-6, d).

%H Charles R Greathouse IV, <a href="/A279542/b279542.txt">Table of n, a(n) for n = 1..400</a>

%F a(n) = A192013(A279541(n)) = A000005(A279541(n)).

%e Let (m|n) = Kronecker(m, n) be the Kronecker symbol.

%e A192013(1) = (-6|1) = 1 = a(1).

%e A192013(5) = (-6|1) + (-6|5) = 2 = a(2).

%e A192013(25) = (-6|1) + (-6|5) + (-6|25) = 3 = a(3).

%e A192013(35) = (-6|1) + (-6|5) + (-6|7) + (-35|1) = 4 = a(4).

%e A192013(175) = (-6|1) + (-6|5) + (-6|7) + (-6|25) + (-6|35) + (-6|175) = 6 = a(5).

%e A192013(385) = (-6|1) + (-6|5) + (-6|7) + (-6|11) + (-6|35) + (-6|55) + (-6|77) + (-6|385) = 8 = a(6).
