In general, which books on group theory have you read? Do you know that quotients G/H only form a group when H is normal in G? How do you plan on representing the elements of G/H? Are you going to return conjugacy classes or simply representatives of them? If simply reps, how will they be selected? Will your representations be deterministic or random? Generally speaking, your description lacks details. > > > > On Mon, Mar 25, 2013 at 9:11 AM, Tarang Patel <tarangro...@gmail.com>wrote: > >> >> >> On Sun, Mar 24, 2013 at 9:09 PM, Ramana Venkata >> <idlike2dr...@gmail.com>wrote: >> >>> Actually we don't have a generic group object as you may have know.
