Section 9.4: Analysis

Conjugacy used here in Section 9.4 seems to be at least partially related to normal groups. For normal groups g^-1 n_1 g=n_2 and n_1 does not necessarily equal n_2 . Here a is said to be conjugate to b if there exists an x\in G such that b=x^-1 a x . There’s a distinct similarity that may have some significance, or we may be able to reword Hungerford’s original explanation of Normality using Conjugacy.
