It is possible to get informations about the status of the computation of the
functions of Chapter <Ref Chap="Methods for matrix groups"/> of this manual.
is the Info class of the &Polenta; package (for more details on the Info mechanism
see Section <Ref Sect="Info Functions" BookName="Reference"/> of the &GAP; Reference Manual).
With the help of the function
<C>SetInfoLevel(InfoPolenta,<A>level</A>)</C> you can change
the info level of <C>InfoPolenta</C>.

If <C>InfoLevel( InfoPolenta )</C> is equal to 0
then no information
messages are displayed.

<Item>
If <C>InfoLevel( InfoPolenta )</C> is equal to 1 then basic informations
about the process are provided. For further background on the displayed
informations we refer to <Cite Key="Assmann"/> (publicly available via the

If <C>InfoLevel( InfoPolenta )</C> is equal to 2 then, in addition to the
basic information, the generators of computed subgroups and module series
are displayed.
