We calculate ground-state properties of nuclei in the Z> 100 region. The most stable superheavy elements are predicted for lower neutron number than in previous investigations, namely 2883(11o~ and 29oY11o,, both with a calculated half-life of around 200 days. A new feature is a local minimum in the ground-state shell correction at Z=110 and N= 162. Elements in this region are therefore expected to show increased stability relative to some earlier expectations.
