$PDET group              (required if NPDET>0 in $GMCPT)                        
                                                                                
    This group defined the "parent" determinants, which                         
will be excited to excitation level NEXCIT.  There must be                      
a total of NPDET determinants given in the group.  Each                         
determinant may have spaces at the front or rear, but not                       
embedded within the string.  An example, presuming NPDET=3,                     
is

   These two groups add (or remove) determinants from the                       
reference list.  The first line in the group tells how many                     
determinants are contained in the group.

These two determinants would be generated if the $PDET list                     
was used with NEXCIT=2 (or higher), but this $REMDET would                      
remove them from the generated total reference CI.
