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...
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 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...
