^aiasu: icosahedral asymmetric unit,

^b ${\mathrm{R}}_{\text{work}}=\frac{{\sum }_{\mathit{\text{hkl}}}||\mathit{\text{Fobs}}|-|\mathit{\text{Fcalc}}||}{{\sum }_{\mathit{\text{hkl}}}|\mathit{\text{Fobs}}|}$

r.m.s.d: root-mean-square-deviation, numbers were generated in Phenix (Afonine et al., 2012).
