Abstract

In the review article on cholesteric blue phases by Stegemeyer et al. [1], table 3 lists [100] as the second largest BPI facet and the largest BPII facet. If such is the case, then, it is important to realize that it is unlikely the body centred cubic phase of BPI has O⁸(I4 ₁32) symmetry and the simple cubic phase of BPII, O²(P4₂32) symmetry [2–4].
