Some Values of Olson's Constant

LetG be a nite abelian group of order n. Erdos conjectured that ev- ery subset A of G with cardinalityjAj p 2n contains a nonempty sub- set with zero sum. The Olson Constant Ol(G) is dened as the smallest k such that every subset ofG of cardinalityk contains a nonempty 0-sum subset. Olson's Constant is analogous to Davenport's Constant D(G), but no repetitions of elements of G are allowed. In this work we give the values of Ol(G) for some groups G. Thus we have Ol(Z n
