help? two-sided plane groups

Hi, I was wondering whether anyone knows of a reference/FTP site/
etc. where the symmetry operations for the 80 two-sided plane groups
could be found.  I realize that the plain :-) old plane groups are 
listed in the International Tables, but I do not seem to be able to 
find more than a listing of the names of the other ones.  

I could work out all of the symmetries, but there are a lot of 
them and it would be bad to make a mistake since I want to do some
computation with them.  Thanks for any help!
