For example, you might also encounter *R3:h* and *R3:r* for hexagonal and rhombohedral axes respectively. Unfortunately, sometimes you might even encounter programs which use *R3* to refer to *hexagonal* axes, and *H3* for *rhombohedral* axes! However, you can always tell the difference by looking -at the unit cell paramters. For some more discussion, including a useful +at the unit cell parameters.

As noted above, it's the *apparent* symmetries of the lattice that matter here. For example, unless the indexing is *very* accurate (within 1/20 of a degree), the following unit cell will need to be merged with point group *222* (or *mmm* to merge Friedel pairs), even though it is -technicall monoclinic: +technically monoclinic: a=63 Å, b=82 Å, c=95 Å, alpha=gamma=90°, beta=90.04° |
