o describe the cosets of the subgroups in parts 1-5: The subgroup z of R
1. Let G be element. Consider the subgroups H = <a) = { a, b, c, d, e} and K = (j)-{ e, j, o, t} the group whose Cayley diagram is shown below, and suppose e is the identity rl Carry out the following steps for both of these subgroups. Let the cosets element-wise. (e) Write G as a disjoint union of the subgroup's left cosets. (b) Write G as a disjoint union of the subgroup's right cosets. (c)...

Answer Question 5 . Name: 1. Prove that if N is a subgroup of index 2 in a group G, then N is normal in G 2. Let N < SI consists of all those permutations ơ such that o(4)-4. Is N nonnal in sa? 3. Let G be a finite group and H a subgroup of G of order . If H is the only subgroup of G of order n, then is normal in G 4. Let G...
ANSWER 1 & 2 please. Show work for my understanding and upvote. THANK YOU!! 1. Consider the subgroups H-〈(123)〉 and K-〈(12)(34)〉 of the alternating group A123), (12) (34)). Carry out the following steps for both of these subgroups. When writing a coset, list all of its elements. (a) Write A as a disjoint union of the subgroup's left cosets. (b) Write A4 as a disjoint union of the subgroup's right cosets. (c) Determine whether the subgroup is normal in A...
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...
