: Every group of order ( p^2 ) is abelian. Solution idea : From 4.3.6, ( |Z(G)| = p ) or ( p^2 ). If ( |Z(G)| = p ), then ( G/Z(G) ) cyclic ⇒ ( G ) abelian (contradiction unless ( Z(G) = G )).

It is tempting to race ahead to Sylow's Theorems, but the core mechanics of permutation representations taught in 4.2 are required to understand how Sylow subgroups interact. Draw the Orbits: For small symmetric groups like S3cap S sub 3 S4cap S sub 4
