Graph of maximal subgroups relating the space groups of the parent phase (highlighted in blue) and distorted phase (highlighted in green) of \mathrm{Sr}_{2} \mathrm{MSbO}_{6} compounds in the P 2_{1} / n and R \overline{3}. For each subgroup any irrep yielding this symmetry is indicated and the primary active irreps evidenced by the Rietveld refinement are highlighted in orange. In the scheme we are using the standard settings of the space groups as the Bilbao Crystallographic Server does for generating these graphs. The P 2_{1} / c is the standard setting of P 2_{1} / n
