\begin{document}$S U(3)$\end{document} higher-order interactions offers a new route to enhance our understanding on γ-soft rotation. In this paper, \begin{document}$ U(5) $\end{document}-like and \begin{document}$ O(6) $\end{document}-like new γ-softness are observed, in which the corresponding energy levels in the ground and quasi-γ bands can be exactly degenerate and have a partial \begin{document}$ O(5) $\end{document} dynamical symmetry. The spherical-like γ-softness is not related to the classical \begin{document}$ O(6) $\end{document} dynamical symmetry. The transitional behaviors of \begin{document}$ B(E2) $\end{document} values of the low-lying levels and quadrupole moment of the \begin{document}$ 2^{+}_{1} $\end{document} state are also discussed. Spherical-like γ-softness can be used to explain the low-lying spectra and \begin{document}$ B(E2) $\end{document} values in 110Cd normal states."> New <i>γ</i>-soft rotation in the interacting boson model with <i>SU</i>(3) higher-order interactions -
