Dear GAP-Forum,
while ConstituentsOfCharacter gives one a list of irreducible
constituents of a character x, I cannot find a function that
computes the multiplicities of irreducibles in x.
An obvious modification of ConstituentsOfCharacter (returning consts
instead of Set(consts)) however does the thing (returning irreducibles with
right multiplicities).
Shouldn't GAP provide such a function?
Best wishes and Happy New Year,
Dmitrii
