I'm looking at the space group #55, Pbam.
In the top of the file (see below) it has listed:
Pbam D^9_2h mmm Orthorhombic
Is this saying that Pbam is consistent with point group mmm?
It does not have three mirrors, it has two glide plane and one mirror.
If I look at the space group, I see that it can create a crystal that has C2h but not D2h.
Am I missing something? Is the "D^9_2h mmm" in the table telling me something other than the point group -- if so, what?
