Let \$G\$ be an additive finite abelian group, and let \$\mbox{disc}(G)\$ denote the smallest positive integer \$t\$ such that every sequence \$S\$ over \$G\$ of length \$|S|\geq t\$ has two nonempty zero-sum subsequences of distinct lengths. We present some recent results and some open problems on \$\mbox{disc}(G)\$.
