  The successive ionization potentials (IPs) and electron affinities (EAs) for
superheavy elements with $111 \leq Z \leq 114$, namely, Rg, Cn, Nh, and Fl are
reexamined using the relativistic Fock-space coupled-cluster method with
nonperturbative single (S), double (D), and triple (T) cluster amplitudes
(FS-CCSDT). For the most of considered quantities, the triple-amplitude
contributions turn out to be important. The Breit and frequency-dependent Breit
corrections are evaluated by means of the configuration-interaction method. The
quantum-electrodynamics corrections to the IPs and EAs are taken into account
within the model-QED-operator approach. The obtained results are within 0.10 eV
uncertainty.
