Problem 3. Subgroups of quotient groups. Let G be a group and let H<G be a normal subgroup. Let K be a subgroup of G that contains H. (1) Show that there is a well-defined injective homomorphism i: K/ H G /H given by i(kH) = kH. By abuse of notation, we regard K/H as being the subgroup Imi < G/H consisting of all cosets of the form KH with k EK. (2) Show that every subgroup of G/H is...
1. 2. Use the Correspondence Theorem to find all subgroups of S that contain K = {1, (12)(3 4), (13)(2 4), (1 4)(2 3)], Draw its lattice diagram If α : G → C6 is an onto group homomorphism and \ker(a)-3, show that \G\ = 18 and G has normal subgroups of orders 3, 6 and 9. Use the Correspondence Theorem to find all subgroups of S that contain K = {1, (12)(3 4), (13)(2 4), (1 4)(2 3)], Draw...
Please answer all the four subquestions. Thank you! 2. In this problem, we will prove the following result: fG is a group of order 35, then G is isomorphic to Z3 We will proceed by contrd cuon, so throughout the ollowing questions assume hat s grou o or ㎢ 3 hat s not cyc ić. M os hese uuestions can bc le nuc endent 1. Show that every element of G except the identity has order 5 or 7. Let...

I have to use the following theorems to determine whether or not it is possible for the given orders to be simple. Theorem 1: |G|=1 or prime, then it is simple. Theorem 2: If |G| = (2 times an odd integer), the G is not simple. Theorem 3: n is an element of positive integers, n is not prime, p is prime, and p|n. If 1 is the only divisor of n that is congruent to 1 (mod p) then...
