Cameron-Liebler sets of generators in the Klein quadric $Q^+(5,q)$

Abstract: We investigate Cameron-Liebler sets of planes in the Klein quadric $Q<sup>+(5,q)$ in PG$(5,q)$. We prove that there are many examples of such Cameron-Liebler sets of planes in the Klein quadric. More specifically, we provide an incomplete list of examples of such Cameron-Liebler sets of planes. By doing so, we also provide some characteristic results regarding these sets in connection with the Klein quadric. These results contribute to an open conjecture posed in [21].
