✦ Synopsis
A subset S = {s 1 , . . . , s k } of an Abelian group G is called an S t -set of size k if all sums of t different elements in S are distinct. Let s(G) denote the cardinality of the largest S 2 -set in G. Let v(k) denote the order of the smallest Abelian group for which s(G) k. In this article, bounds for s(G) are developed and v(k) is determined for k 15 by computing s(G) for Abelian groups of order up to 183 using exhaustive backtrack search with isomorph rejection.

Let G be an abelian group of order k. How is the problem of minimizing the number of sums from a sequence of given length in G related to the problem of minimizing the number of k-sums? In this paper we show that the minimum number of k-sums for a sequence a 1 , . . . , a r that does not have 0 as a
