molecular replacement non-standard symmetry

I have collected data that shows 4/mmm. I also see h=2n (and k=2n)
absences. I am missing data on the l axis. To play safe, I processed
the data in P4212 (90) and tried to do molecular replacement in all the
allowed space groups:
P4212(90), P41212(92), P42212(94) and P43212(96)
I could not find an obvious solution.
My colleague told me that one needs to try "non-standard" space groups
as well. Does it mean I also need to do something like:
P4221, P41221, P42221 and P43221?
If yes, where (or how) can I find out the symmetry operations for these
Thank you very much.
