%N G.f.: A(x) = ( G(x)^5 - G(x^5) - 5*x*((1-x^4)/(1-x))/(1-x^5) )/(25*x^2) where G(x) is the g.f. of A110631.
%C A110631 is formed by selecting every 5th term of A083945; surprisingly, the self-convolution 5th power of A110631 is congruent modulo 25 to A083945, which consists entirely of numbers 1 through 5.
%Y Cf. A110631, A083945.
