In 1893 it was shown by Moore that the only commutative, associative division algebras with a finite number of elements are the well-known Galois fields [10, p. 220]. Twelve years later it was shown by Wedderburn that every associative division algebra with a finite number of elements is commutative [11], and hence a Galois field. It is conceivable that these results, particularly the theorem of Moore, motivated some of the work done by Dickson and published in two papers in 1906 [4;5]. The work referred to is an attempt to determine all commutative, non-associative1 division algebras with a finite number of elements.
