TeX note: \setminus is, as the name suggests, for set complements. Use \backslash for a left quotient. (Compare $H\setminus G$ H \setminus G to $H\backslash G$ H\backslash G.) I have edited accordingly. \\ Also, what is $B$ in your question? Just another subgroup?

`\setminus` -> `\backslash`, and other proofreading
