Look at a Python tutorial and/or reference for how to write to files and
how to format strings.

All I know is what's in the documentation
("SymmetricGroupRepresentation?"). If that doesn't help, see the cited
paper. If that still doesn't help, you might ask in sage-combinat-devel, or
at least ask here with a more informative subject line. Maybe that will
catch the eye of someone who knows more about the relevant issues.
