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...
I have done the first part showing that it is an action, can anyone help the rest of them please! Many thanks!!! 8. Let H be a subgroup of a group G and let X be the set of left cosets H of H in G. (i) Show that g.xH ::: grH (g, x є G) defines an action of G on X. (ii) Show that there is a single orbit, X, under this action (ii) Show that the stabilizer...
abstract algebra show your work 3. Let H be a subgroup of G with |G|/\H = 2. Prove that H is normal in G. Hint: Let G. If Hthen explain why xH is the set of all elements in G not in H. Is the same true for H.C? Remark: The above problem shows that A, is a normal subgroup of the symmetric group S, since S/A, 1 = 2. It also shows that the subgroup Rot of all rotations...
Abstract Algebra 1 a) Prove that if G is a cyclic group of prime order than G has exactly two subgroups. What are they? 1 b) Let G be a group and H a subgroup of G. Let x ∈ G. Proof that if for a, b ∈ H and ax = b then x ∈ H. (If you use any group axioms, show them)
Hello, please kindly show all your steps without skipping any part. Please also cite any defintions if necessary generously to help me understand this question. Thanks in advance. 4) [3 marks) Recall that in Question 2a from Assignment 6, you proved that H = {{0), (4), (8]} is a subgroup of Zi2. Write out all of the distinct cosets of H in Z12. Determine (Z12: H).
hello guys, please help me solve this question, please guys I need your help. this is one questions with 2 parts as shown, thank you part1 You are planning on installing a new above-ground swimming pool in your backyard. The pool will be rectangular with dimensions 29.0 m x 10.0 m. It will be filled with fresh water to a depth of 2.20 m. In order to provide the appropriate structural support, you wish to determine the following. (a) Determine...
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...
please solve it very clear with explain your answer abstract algebra 2. Suppose that G and G' are groups and N G, N' 4G'. Prove that (G x G')/(N x N') = G/N x G'/N' <H<G with N 4G. Prove that H/N is a subgroup of 4. Suppose that G is a group, N G/N.
