✦ Synopsis


When generalizing the internal direct product from groups to all groupoids Ε½ . binary systems , it has been customary to imitate the group case by making restrictions, especially the existence of an identity element. This article develops what seems a natural basic definition of internal direct product, then uses it as a background against which to compare more popular restricted versions.

We determine all maximal subgroups of the direct product G n of n copies of a group G. If G is finite, we show that the number of maximal subgroups of G n is a quadratic function of n if G is perfect, but grows exponentially otherwise. We deduce a theorem of Wiegold about the growth behaviour of the

## Abstract In this article we study the product action of the direct product of automorphism groups of graphs. We generalize the results of Watkins [J.
