Which of the following statements are true? Give reasons for your answers. Marks will only be given for valid justification of your answers. i) In a non-abelian group of order 27, the identity conjugacy class is the only class with a single element. ii) A finite field with 16 elements has a subfield with 8 elements. iii) The number of distinct abelian groups of order p"p...p is n,n,...n, where the P, are distinct primes and n, e N. iv) If G is a finite group, such that Z(G) = G, then o(G) is a prime. v) If X is a G-set, Ga group, and YCX is G-invariant, then X\Y is G-invariant.
