DESCRIPTION:In this talk\, we will provide an overview of results in gener
 alised graph groups\, for graphs with |V|=|A|-1 (where |V| is the number o
 f vertices and |A| is the number of arcs)\, and Circulant digraphs. This t
 alk will turn its attention to prove whether these corresponding groups of
  the possible graphs under  |V|=|A|-1  are finite cyclic group or not. In 
 some cases we are able to show that they are finite cyclic group (22 of 31
  possible graphs)\, in others that the rank is at least 1 or 2. We will al
 so demonstrate the order of these groups. In terms of Circulant digraphs\,
  we will give the exact order for generalised graph groups corresponding t
 o Circulant digraphs.
