1. The problem statement, all variables and given/known data Q: In Qu, write down the elements in all the right cosets and all the left cosets of <j>. 2. Relevant equations Let H ≤ G. A coset of H is a subset of G of the form Hg for some g ∈ G. where ≤ denotes subgroup. 3. The attempt at a solution I need help understanding what all this means. Can someone give me an example of what I should be looking for / doing here? I don't understand what they mean by the group Qu. Is this some group u multiplied by Q? Or just the group Qu. etc.
