In these solutions it refers to See "Some notes on $D_n, S_n$ and $A_n$". Does anyone know where these notes can be found? They sound extremely useful.

EDIT: Does anyone know of any resources like this that give many examples of how to find conjugacy classes, normal subgroups, ismorphisms between groups and subgroup for the above groups?
