**Abstract:** Let G be a finite abelian group, and let S µ G be a subset of distinct nonzero
elements of G. If each element g 2 G of the group can be written as a nonempty
sum of elements from S, then we say S spans G nontrivially. Denote the maximum
cardinality of a subset S which fails to span G nontrivially by e(G), as studied by
Griggs in [5]. Griggs noted that the value of e(G) is known for all finite abelian groups
G except for G = Z=pqZ where p; q are primes such that p+b2pp ¡ 2c+1 < q < 2p.
We determine the value of e(G) for such groups.
