Hello there,
Don't you have extinctions along the axes allowing you to distinguish between the possible space groups? Or are the reflections along the reciprocal axes missing from the data set you have collected? Normally this is how one decides on the space group in orthorhombic 222, by checking the systematic absences.
[is Nathan Zaccai in your institute? If so give him my regards]
Fred.
