Let R be a commutative ring with 1, and let R = t + t 2 RΝ tΝ‘ be the group of normalized formal power series over R under substitution. In this paper we investigate the connection between the ideal structure of R and the normal subgroup structure of R . In particular, we show that, if K is a finite f
