Dear Roghiyeh,

A lot of the information you want is probably on my Database ofgroups up to order 100 at

http:\\www.cs.biu.ac.il\~mschaps\math.html

In particular, the dihedral, semidihedral, and generalized quaterniongroups are identified, some sort of description by extensions is given,and user friendly relations with a normal series (plus character table, blockdecomposition, ect.)

Unfortunately, this database was created a long time ago in GAP3, and souses the old numbering of the solvable groups. However, there is aan easy way to get the old number

gr := SmallGroup([32,6]);

<pc group of size 32 on 5 generators>

Gap3CatalogueIdGroup(gr);

[ 32 , 46 ]

I seem to remember that there is a function going the other way, but Idon't find it in the online GAP4 manual.


                                Sincerely,
                                Mary Schaps

 In fact I would like to know what is the isomorphism of Gi with the well-known 
groups (for example symmetric groups,dihedral groups,...)

 I am looking forward to hearing from you.
 With Best Regards,
 S. R. Adhamy
