a, c, e columnar and b, d, f Fddd phases of compounds (a, b) IC3/14, (c, d) FCN16 and (e, f) FO16. Inset in a depicts two developable domains with (1) a s = +1 disclination and (2) two +½ disclinations, the latter indicating stiffer columns; black lines are column trajectories. Inset in b shows orientation of indicatrices of the λ-plate and the colored fans. Scale bar in b applies to all Figures. See more textures in Supplementary Section 2.
