Why does benzene have a D6h point group?
Does it have two or more $C_2$ axes with $n&gt;2$?


This question is asking if there is more than one $C_{n&gt;2}$ axis not if there is more than one $C_{n&gt;2}$ symmetry operation.

Yes, benzene has some $C_3$ operations. However, as pointed out in the comments, the $C_3$ axis lies along the $C_6$ axis - both run through the center of the ring perpendicular to the plane of the molecule. This axis is also a $C_2$ axis. There is only one $C_{n&gt;2}$ axis - it just happens to be both a $C_6$ and a $C_2$ axis. All other rotation axes in benzene are $C_2$.
