%N Row 4 of table A124560; also, the self-convolution 4th power equals A124554, which is row 4 of table A124550.
%C In table A124560, the g.f. of row n, R_n(y), simultaneously satisfies: R_n(y) = Sum_{k>=0} y^k * [R_{n*k}(y)]^(n*k) for n>=0.
%F G.f.: A(x) = Sum_{k>=0} y^k * [R_{4k}(y)]^(4k), where R_n(x) is the g.f. of row n in table A124560.
%Y Cf. A124560 (table); other rows: A124551, A124562, A124563, A124565, A124566.
