Supplementary Figure 1

Relative elastic constants for all phases, functionals, and previous computational predictions. Exact values can be found in the Supplementary Table III. Previously predicted values are reported for cubic[17-19], monoclinic[17], orthorhombic Pca21[17], orthorhombic Pnma[17,20], and tetragonal[17]. To the best of our knowledge, the elastic constants for orthorhombic Pbca have not been reported previously.
