Abstract
The ground-state properties of superheavy nuclei are investigated within various parametrisations of relativistic and nonrelativistic nuclear mean-field models. The heaviest known even-even nuclei starting with $Z \! = \! 98$ are used as a benchmark to estimate the predictive power of the models and forces. From that starting point, deformed doubly magic nuclei are searched in the region ${100 \! \leq \! Z \! \leq \! 130}$ and ${142 \! \leq \! N \! \leq \!190}$ .
