Table 4. The groupoid 
in table form.
Only one table is shown, as the table applies to all three connected components. Intrinsic translations and positions of geometric elements are given with respect to the basis of the HT phase. Molecules and operations are given modulo the translation lattice of the LT phase. Molecules obtained by a 
operation of the LT phase are marked with a prime.
