Electron diffraction patterns from (a) the λ and (b) the τ(μ) approximants taken at 100 kV along the c axis, on the same scale and with similar orientation. The corresponding strongest diffraction spots in the two approximants are marked by arrow heads. The diffraction pattern of λ in (a) shows only p6 symmetry while that of τ(μ) in (b) shows p6m symmetry. Note however that the strongest diffraction spots in λ (a) have approximate p6m symmetry.
