%N If n can be written in the form r^i-s^j (see A074981), where r,s,i,j are integers with r>0, s>0, i>1, j>1 choose the representation with smallest r^i (in case of ties, minimize i and j); or if n is not of this form set r=s=i=j=0; sequence gives values of r.
%C The zeros are only conjectures (cf. A074981).
%C Use 4^2 rather than 2^4, etc.
%e 1 = 3^2 - 2^3, 2 = 3^3 - 5^2, 3 = 2^2 - 1^2, 4 = 2^3 - 2^2, etc.
