More Space-Group Corrections: From Triclinic to Centred Monoclinic and to Rhombohedral; Also From P1 to P-1 and From Cc to C2/c

We present 14 examples of crystal structures that were originally described as triclinic, but are properly described as either C-centred monoclinic (ten examples) or rhombohedral (four examples). There is also one example each of changes from P1 to P1 and from Cc to C2/c.
