The axes of Pnma (62) space group (in the International Tables for Crystallography) can be re-defined so that the space group becomes a non-standard setting Pbnm. However, both Pnma and Pbnm have the exact same symmetry with the axes defined differently.

Table 3013b lists four different crystals in the same space group (Pnma).

Figures 3013a-b shows the simulated electron diffraction patterns of the four crystals, listed in Table 3013b, in ,  and  zone axes, respectively. From these images, we can have some ideas about the diffraction patterns of different crystals with the same space group. For instance, the d-spacings with similar reflections are different for the four crystals due to the differences between their lattice parameters. Furthermore, the rows of the reflection spots marked by the red arrows, in Figure 3013a, have different intensities among the four different crystals. Note that the darkness of the spots indicates their intensities.
