Wayne,

That is exactly right.  I am impressed.  I didn't see that at all and
I had my copy of the international tables open in front of me for the
last half hour.  The symmetry of that space group does indeed require
what you say.  And it provides Andreas with a work-around.

I still think that Atoms should not have failed in that situation,
however.
