%S 2,4,8,19,51,141,392,1079,2957,8072,21987,59825,162695,442342,1202521,

%T 3268920,8885999,24154826,65659826,178482140

%N Complement of A269020: numbers not of the form ceiling(n^(1+1/n)).

%C The limiting ratio is e (see comment in A059921).

%e The term 8 appears because A269020(5)=7 and A269020(6)=9.
