  Ground state properties of the superheavy elements (SHE) with Z from 108 to
128 and N from 150 to 192 are investigated using both the Skyrme-Hartree-Fock
method with a density-independent contact pairing interaction and the
macroscopic-microscopic approach with an average Woods-Saxon potential and a
monopole pairing interaction. Detailed analysis of binding energies, separation
energies, shell effects, single proton and neutron states, equilibrium
deformations, alpha-decay energies, and other observables is given.
