While using PSL or PGL, how they are different from SL and GL . It has been said that PSL is quotient group with out zero transform.
32.
The quotient group is usually denoted by Out ( " G " ); the non-trivial elements are the cosets that contain the outer automorphisms.
33.
This has the intuitive meaning that the images of " x " and " y " are supposed to be equal in the quotient group.
34.
The effective symmetry group is then the quotient group \ mathrm { S } _ 4 / \ mathrm { K }, which is isomorphic to S 3.

Furthermore, since the kernel of the action ( ) is the subgroup { ?" I " }, then passing to the quotient group gives the group isomorphism
38.
If is normal, so that the-double cosets are the same as the elements of the quotient group, then the product on is the product in the group algebra.

It has been established a long time back that the wikistalker A . K . Nole later edited as Quotient group and than a large variety of sockpuppets listed in the archives here.

Thus, the quotient group " G " / " N " is the group of three colors, which turns out to be the cyclic group with three elements.
