NEED HELP WITH UNDERGRADUATE LEVEL GROUP THEORY?If you want something specific, try the search bar! Else, try:

Basic definitions in group theory page. There'smuch much morein the wiki!

Pages on symmetric group:S3 (see also subgroups, elements, and representations), symmetric group:S4 (see also subgroups, elements, and representations), dihedral group:D8 (see also subgroups, elements, and representations),symmetric group:S5, quaternion group, alternating group:A4, alternating group:A5, and many more.Incomplete(not fully finished) guided tour for beginners; the part prepared so far goes over the basic definitions of groups, subgroups, cosets, basic results such as Lagrange's theorem, and a little more, along with stimulating exercises.
