%N Positions of the terms of A090845^3 in A090845, where A090845 is equal to the union of the self-convolutions A090845^2 and A090845^3, in ascending order by size, starting with A090845(0)=1.
%C What is the value of limit a(n)/n ? Example: a(12000)/12000 = 2.3758333...

%F A090845(a(n)) = A222083(n) for n>=0, where A222083 is the self-convolution cube of A090845.
%e a(4)=10 since A090845^3(4)=A090845(10)=51, where
%e A090845={1,1,2,3,5,9,10,20,22,40,51,...} and
%e A090845^3={1,3,9,22,51,114,230,468,885,1674,3045,5418,...}.
