It is well known that semigroups are very useful in the study of automata. These semigroups consist of mappings from the state set Q of the automaton into itself. If, as is often the case, Q bears the structure of a group, we are studying mappings of a group into itself and the natural algebraic tool to use is a near-ring. In this paper our aim is to show how natural near-rings and group automata can be linked by generalizing ideas of M. Holcombe [Proc. Edinb. Math. Soc., II. Ser. 26, 15-24 (1983; Zbl 0491.16034)].
