$FMM group      (relevant if QFMM selected in $INTGRL)
 
    This group controls the quantum fast multipole method
evaluation of Fock matrices.  The defaults are reasonable,
so there is little need to give this input.
 
ITGERR = Target error in final energy, to 10**-(ITGERR)
         Hartree.  The accuracy is usually better than
         the setting of ITGERR, in fact QFMM runs should
         suffer no loss of accuracy or be more accurate
         than a conventional integral run (default=7).
 
QOPS   = a flag to use the Quantum Optimum Parameter
         Searching technique, which finds an optimum FMM
         parameter set. (Default=.TRUE.)
 
If QOPS=.FALSE., the ITGERR value is not used.  In this
case the user should specify the following parameters:
 
NP     = the highest multipole order for FMM (Default=15).
 
NS     = the highest subdivision level (Default=2).
 
IWS    = the minimum well-separateness (Default=2).
 
IDPGD  = point charge approximation error (10**(-IDPGD))
         of the Gaussian products (Default=9).
 
IEPS   = very fast multipole method (vFMM) error,
         (10**(-IEPS)) (Default=9)
