%N A088055 a(n) = G(n) - A(n), where G(n) = Sum of the first n terms of a geometric 
               progression with first term n and common ratio n. A(n) = Product 
               of first n terms of an arithmetic progression with first term n and 
               common difference n.
%F A088055 a(n) = A031972(n) -A061711(n). a(n) = {(n^(n+1)-1)/(n-1) - 1} - { n!*n^n}
