Figure 1 (by doing the above [log, s] times we ensure that s/2!!825! < 1, and since s > 1 we have 3s > 3/log,(s)|). Therefore for all r; sufficiently large, Clearly there are only finitely many sum-dominant subsets Ky, with r; < 4s; the analysis is completed by showing there are no sum-dominant sets with r; > 4s. Imagine there was a sum-dominant Kj; with a,, > a4;. Then / is the union of a set of elements S = {51,...,5m}in A; and a,, in Ay. As doses 8 < a,,, by Lemma 3.1 we find Ky is not a sum-dominant set.
