AFAIK, the information in the manual is correct. My guess is that different parts of the Firefly code number the irreps differently. The numbering on page 121 pertains to the TDHF/TDDFT/CIS code, while the second numbering you refer to (ISTSYM=4 for Bu in C2h) pertains to the (X)MCQDPT2 code. Perhaps Alex can provide more information (or correct me if I'm wrong).

Page numbers will be added in the next update.


Kind regards,
Thom
