# An Application of Burnside Rings in Elementary Finite Group Theory

**Abstract.**
A canonical map from the Burnside ring of a finite cyclic group
*C* into the Burnside ring of any finite group *G* of the same
order is exhibited and it is shown that many results from elementary
finite group theory, in particular those claiming certain congruence
relations, are simple consequences of the existence of this map.
In addition, it is shown that this map defines an isomorphism from
the Burnside ring of *C* onto the subring of the Burnside ring of *G*,
consisting of those virtual *G*-sets *x* which have the same number of
invariants for every two subgroups *U* and *V* of *G* having the same order,
if and only if *G* is nilpotent. Finally, a rather natural extension to
profinite groups is indicated.
The paper was not in final form, its final form has been published
1992 under the same title in:
