#F RecognitionAISMatrixGroup(G, inds, wantmat, wantgroup)
##
## version of RecognitionIrreducibleSolubleMatrixGroupNC which
## only works for absolutely irreducible groups G. This version
## allows to prescribe a set of absolutely irreducible subgroups
## to which G is compared. This set is described as a subset <inds> of
## IndicesAbsolutelyIrreducibleSolubleMatrixGroups(n, q), where n is the
## degree of G and q is the order of the trace field of G. if inds is fail,
## all groups in the IRREDSOL library are considered.
##
## WARNING: The result may be wrong if G is not among the groups
## described by <inds>.

#F RecognitionIrreducibleSolubleMatrixGroup(G, wantmat, wantgroup)
##
## Let G be an irreducible soluble matrix group over a finite field.
## This function identifies a conjugate H of G group in the library.
##
## It returns a record which has the following entries:
## id: contains the id of H (and thus of G),
## cf. IdIrreducibleSolubleMatrixGroup
## mat: (optional) a matrix x such that G^x = H
## group: (optional) the group H
##
## The entries mat and group are only present if the booleans wantmat and/or
## wantgroup are true, respectively.
##
## Currently, wantmat may only be true if G is absolutely irreducible.
##
## Note that in most cases, the function will be much slower if wantmat
## is set to true.
