%N Positive integers not appearing in sequence A098572, which calculates the values of floor(sum(m^(1/m),n=1..m)).

%e floor(1^(1/1)+2^(1/2)+3^(1/3))=3, floor(1^(1/1)+2^(1/2)+3^(1/3)+4^(1/4))=5 and so 4 is a member of this sequence.

%p ans:=[]: a:=0: last:=0: n:=1: do: a:=a+evalf(n^(1/n),50): if floor(a)-last>1 then ans:=[op(ans),floor(a)-1]: fi: last:=floor(a): n:=n+1: od:
