The pseudo BRST invariant C^mnp_{1|2,3,4,5,6,7} contains more than
37 million terms of polarization and momenta.

The uncompressed plain text file weights 2.8GB and it can be
a bit challenging to load even with FORM.

If you have not yet been discouraged at this point, you can
request this file privately from Carlos Mafra and Oliver Schlotterer.
Good luck!
