Table is the erroneous result for SiO 2 (mp-1256614), which is quartz (alpha)-like crystal structured. This crystal is specifically characterized with its rings composed of connected SiO 4 tetrahedra. Its space group P 6 3 {mmc was retrieved as the third scored one, and both the first scored P 6{mcc and P 6 3 {mmc have the hexagonal crystal system and have the point group of D 6h . The second scored space group P 6mm has the same crystal system but its point group is C 6v , and so the 6-fold rotation axis was suggested by CLICS. The problem is that, although the second and third scored local atomic environments are correct, the first scored one is perfectly wrong and also not similar to any local geometries in the crystal: The only [METALLOID] is Si and is bonded in the common SiO 4 tetrahedra. We found the same errors for e.g. CapSiO 2 q 6 , BaFeSi 4 O 10 , and LiZr 2 pPO 4 q 3 (Table ) as their fourth scored local atomic environments, and for other examples with the same type of text including long sentences that describe connected polyhedra. The connected tetrahedra might have been learned as a distinct geometric entity not as a single tetrahedron connected each other.
