Summary:. In a previous article, published in Phys. Rev. C 94 , 014309 (2016), we have shown for the first time that the best dynamical trajectory during the deformation toward fission of the superheavy nucleus 286 Fl is a linearly increasing radius of the light fragment, R 2 . This macroscopic-microscopic result reminds us about the α or cluster preformation at the nuclear surface, assumed already in 1928, and proved microscopically many times. This time we give more detailed arguments for the nucleus 282 Cn. Also similar figures are presented for heavy nuclei 240 Pu and 252 Cf. The deep minimum of the total deformation energy near the surface is shown for the first time as a strong argument for cluster preformation.
