That is, when the number larger than 1 is specified, it is used as the divisor for the interval 0 to 0.5. For the FCC and BCC lattices, the zone boundary is 1 rather than 0.5. Above command and keywords work as well. Specify point group symbol as keyword. In future, three-fold axis symmetry as the subgroup of Oh group will be available, but not in the present version.
Symbol is the same as r-space symmetry.
However, in the presend version, this verbose decsription is retained. Specify 14 Bravais lattices in 3D or 5 lattices in 2D systems. For the ionic systems, the long range Coulombic interactions beyond RLIM must be taken into account. PCHG command do this correction by the point charge approximation. The former is added to the Fock matrix, and the latter is added to the total energy expression.
