DESCRIPTION:In this talk\, we will provide an overview of resu
lts in generalised graph groups\, for graphs with
|V|=|A|-1 (where |V| is the number of vertices and
|A| is the number of arcs)\, and Circulant digrap
hs. This talk will turn its attention to prove whe
ther these corresponding groups of the possible gr
aphs under |V|=|A|-1 are finite cyclic group or
not. In some cases we are able to show that they a
re finite cyclic group (22 of 31 possible graphs)\
, in others that the rank is at least 1 or 2. We w
ill also demonstrate the order of these groups. In
terms of Circulant digraphs\, we will give the ex
act order for generalised graph groups correspondi
ng to Circulant digraphs.
