in detail. The need for a simultaneous consideration of many shape variables in PES’s calculations is common to all nuclear models, including self-consistent theories based on some effective interactions [@Schunck]. The results on fission saddles obtained up to now in the SH region clearly show the great importance of triaxial deformation, neglected in many published work. A recent study [@BroSkal] of barriers within both the MM Woods-Saxon and Skyrme SLy6 Hartree-Fock plus BCS models shows that triaxiality is even more crucial beyond $Z =$ 126.

A description of our method of calculations is given in section II. The results, details of the additional calculations, and comparisons with other calculated barriers are presented and discussed in section III. Finally, the conclusions are summarized in section IV.

The Method
==========

Multidimensional energy landscapes are calculated within the MM model besed on the deformed Woods-Saxon potential [@WS]. The Strutinski shell and pairing correction [@STRUT67] is taken for the microscopic part. For the macroscopic part we used the Yukawa plus exponential model [@KN] with parameters specified in [@MUNPATSOB]. Thus, all parameter values are kept exactly the same as in all recent applications of the model to heavy and superheavy nuclei
