kcrismanI have been computing some characters by hand, but just can't seem to figure out how they relate to the standard "induced character" constructions I can find. Small example: For $G=S_4$ and the cyclic subgroup $H=\langle(1234)\rangle$, references indicate that the permutation character (well, ch...
