Dear Amy,

in addition to Frank Luebeck's message,
I would like to point out that the CHEVIE package is not
necessary to compute permutation characters from character
tables.
For example, also the following program does the job.
The arguments are a group 'G' and a subgroup 'S'
(which are not necessarily permutation groups).

PermChar := function( G, S )
    local tS, tG;
    tG:= CharTable( G );
    tS:= CharTable( S );
    return Induced( tS, tG, [ List( tS.classes, x -> 1 ) ],
                    FusionConjugacyClasses( S, G ) )[1];
end;

Kind regards
Thomas Breuer
