An I-E group is a group G in which the endomorphism near-ring generate
d by the inner automorphisms of G equals the endomorphism nearing gene
rated by the endomorphisms of G. In this paper we obtain a result char
acterizing when a semidirect product of I-E groups of relatively prime
orders is an I-E group. We then use this result to show that a semidi
rect product of cyclic groups of relatively prime orders is an I-E gro
up.
