hey,

i'm trying to study for my up coming exams with these past papers but i've gotten stuck with part c,

i've tried a bunch of different spanning tree's some gave better generators and some gave worse but the ones in the picture were the first ones i found,

i've been trying to use the generators to show that the its not possible to get the conjugate of one of the provided elements of H by multiplying the generators but it hasn't gotten me anywhere,

i also have a feeling the answer to part d) is the whole group F but im not sure why it's just a guess.

could anyone give me a hand working out these two parts?

thanks in advance
