Question

Transcribed Image Text:Let G = D10 x Z/7Z, where, as usual, D10 = (a, b | a³ = b² = e, ba = a*b).
Let H = ((b, 1)) and K = D10 × {0}.
(a) Draw a partial lattice diagram of subgroups of G that includes the
subgroups H and K. Include also HN K and (H, K). Label the
edges with appropriate numbers, and give reasons for what you have
done.
In what follows, you may refer back to your diagram.
(b) What is NG(H), the normalizer of H in G? Why?
(c) Is NG(K) = G?
(d) What is |clG(b, 1)|? Note that clg(x) is the conjugacy class of x in
G and that we are only interested in the order of this set.
(e) Can you add the subgroup L = ((a, 0)) to your lattice diagram?
