So for future reference I'm looking each time for a coset representative to form the quotient group - I hope this is the right term to use here ?

Okay thank you :) . Sorry , just one more quick question ! Would there be other valid answers ? I'm not sure if this is correct but since say we have shown N(24 )= N(13) , we could equally have an equivalent answer for D4/N ?

Thanks for your reply ! Thanks for the welcome . Oops yeah sorry meant right cosets sorry . Well I think they are the same because N(24 ) = {( (24),(13)}=N(13) ? So would this be a suitable answer d4/N={N , N(1432) , N(12)(34) , 24(N)} ?

Homework Statement Let D4 = { (1)(2)(3)(4) , (13)(24) , (1234) , (1432) , (14)(23) , (12)(34) , (13), (24) } and N=<(13)(24)> which is a normal subgroup of d4 . List the elements of d4/N . Homework Equations The Attempt at a Solution I computed the left and right cosets to...
