A screenshot of the partial output of the program LSITESYM, showing the character table of the point group mmm, isomorphic with the site-symmetry group of the Wyckoff position 2c (0, ½, 0) of the layer group p4/mmm (No. 61). The irreps are labelled according to the notation of Mulliken (1933) and Koster et al. (1963). |
