§0 Introduction
The relationship between the endomorphisms and automorphisms of algebraic objects
has long been a subject of interest. In 1963 Fuchs [3] raised the question of when the
automorphism group of an abelian group (additively) generates the endomorphism group.
Further interest in a different direction on the relationship between automorphisms and
endomorphisms of an abelian group was raised by Kaplansky’s introduction [8] of the
notions of transitivity and full transitivity. The problem of Fuchs and related generalizations
have produced ongoing interest and there is an existing literature of which [1], [2],
[6], [7], [11] are the principal results.
