E. Imetroduction Let G be a finite group and SetfG the set of isomorphism classes of all finite G-sets. Then SetfG is a semi-ring with addition and multiplication induced by the disjoint union and the cartesian product, respectively. The Burnside ring A(G) is defined to be the Grothendieck ring of SetfG. Let A(G)* be the group of units in A(G). For a fixed TESetfG, we have an exponential map ( )T:SetfG-SetfG (Sl-ST) where S' ={f:T-S]f; set theoretic map} with G-action g. f: T-S (t ]---+gLIC(g-it)).
