#F ConjugacyClassesSubwreath(<F>,<M>,<n>,<autT>,<T>,<Lloc>,<comp>,<emb>,<proj>)
##
## This function computes the classes of a subwreath groiup. The interface
## is quite technical because the subwreath decomposition is passed already
## with it: <F> is the factor group, <FM> the normal subgroup in it (direct
## product of the <n> groups isomorphic <T>). <T> is one of these and
## <autT> the action of <FM> on the first component, the components are
## given in <comp>, <emb> and <proj> are embeddings and projectios for the
## direct product.
DeclareGlobalFunction("ConjugacyClassesSubwreath");

##
#F ConjugacyClassesFittingFreeGroup(<G>)
##
## computes the classes of a group <G> which has no solvable normal
## subgroups. It returns a list whose entries are of the form
## [<rep>,<centralizer>].
DeclareGlobalFunction("ConjugacyClassesFittingFreeGroup");

##
#F ConjugacyClassesViaRadical(<G>)
##
## computes the classes of a group <G> by lifting the classes of G/Rad(G)
## using affine actions. It returns a list of conjugacy classes.
