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...
Can anyone help with this questions please! Many thanks! Sorry I don't get it, what is chi? c) Suppose now that |G| p" m where hcf (p, m) =1. (iv) Take Fo such that hef (lOrbc (Fo)|, p) = 1. i. Show that there exists A E Orbo(Fo) such that 1 E A ii. Let P Stabc(A). Show that |P = p" and P = A i. Show that Orbc(Fo) = G/P, the set of left cosets of P in...
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...
