Stieltjes constants change sign between StieltjesGamma(k) and StieltjesGamma(k+1).
FORMULA
a(n) = -1 + Sum_{i=0..n-1} A114524(i).
EXAMPLE
0 is a term because StieltjesGamma(0) = 0.577216 (positive) and StieltjesGamma(1) = -0.0728158 (negative).
5 is a term because StieltjesGamma(5) = 0.000793 (positive) and StieltjesGamma(6) = -0.0002387 (negative).
MATHEMATICA
aa = {}; Do[If[Sign[StieltjesGamma[n]] != Sign[StieltjesGamma[n + 1]], AppendTo[aa, n]], {n, 0, 755}]; aa
