All variables are integers. Used in all programs. Used in post-SCF programs only. This common block contains information about the distribution of molecular orbitals among the various symmetry species. The lengths of both alpha alpha and beta beta virtual-virtual vectors which are overall totally symmetric .
All variables are integers.
Used in post-SCF programs only. This common block contains some rudimentary information which pertains to molecular symmetry. All variables are integers. Used in post-SCF programs only. This common block contains information which is extremely useful in the coding of contractions.
