Abstract 



Given the ring of integers O (K) of an algebraic number field K, for which natural numbers n there exists a finite group G aS,aEuro parts per thousand GL(n, O (K) ) such that O (K) G, the O (K) span of G, coincides with M(n, O (K) ), the ring of (n x n)matrices over O (K) ? The answer is known if n is an odd prime. In this paper we study the case n = 2; in the cases when the answer is positive for n = 2, for n = 2m there is also a finite group G aS,aEuro parts per thousand GL(2m, O (K) ) such that O (K) G = M(2m, O (K) ).
