Dear GAP Forum,

In addition to my previous question,

Could someone provide me with a reference to the algorithm used

in the function Eigenvalues which computes the eigenvalues

of a representative of a conjugacy class in a given irreducible

representation?

I would like to know if there is a quickier way to compute the

characteristic polynomial f=f(G) of a representative G

of a conjugacy class mentioned

above, than using Eigenvalues().

(The latter function involves using algebraic numbers, whereas it might happen

that f has rational or integer coefficients , i.e. all the irrationalies cancel)

Thanks in advance,

Dmitrii Pasechnik <D.Pasechnik@twi.tudelft.nl>
