This card can be used to restrict the occupation patterns in the reference
configurations. Only configurations containing between *nmin* and *nmax*
electrons in the specified orbitals *orb*, *orb*, , *orb*
are included in the reference function. If *nmin* and *nmax* are negative,
configurations with exactly abs(*nmin*) and abs(*nmax*) electrons in the
specified orbitals are deleted. This can be used, for instance, to omit singly
excited configurations. The orbitals are specified in the form *number.sym*,
where *number* is the number of the orbital in irrep *sym*. Several
`RESTRICT` cards may follow each other.

The `RESTRICT` cards must follow the `WF` or `REF` cards to
which they apply. The general order of these cards is

If a `RESTRICT` cards precedes the `WF` card, it applies to all reference
symmetries. Note that `RESTRICT` also affects the spaces generated by `SELECT`
and/or `CON` cards.
