The construction of any finite translation plane depends on the appropriate determination of a partition P E of a Galois field E , together with a set A of automorphisms of E as a vector space. In this paper we obtain sufficient conditions on P E and A , so that a translation plane is produced. They are also necessary conditions when A = 1 . Particularly, we examine the case where E is a two-dimensional vector space. We prove that no translation planes are constructible by a single automorphism,...
