In the factorial ring of Dirichlet polynomials we explore
the connections between how the Dirichlet polynomial
associated with a
finite group factorizes
and the structure of .
If is irreducible,
then
is simple. We investigate whether the converse is true, studying
the factorization in the case of some simple groups. For any prime
we show
that if ,
then and
is irreducible.
Moreover, if ,
then is simple,
but is reducible
whenever
and .
