T2-Groups And a Characterization of the Finite Groups of Moebius Transformations
Peter Lorimer · Canadian Journal of Mathematics · 1965
In recent years a number of algebraic characterizations of the groups of Moebius transformations over finite fields have been given in the literature; see (1, 3, 6). H. W. E. Schwerdtfeger has noticed (4) that the group G of Moebius transformations over the real, complex, and certain other fields has the property:
