Dear Asma, There is a question "Permutability Graph with GAP" on Mathematics Q&A site, which you may find useful:
http://math.stackexchange.com/q/1149728/ You may start with modifying the construction of the adjacency matrix for a different vertices set and different condition for the vertices to be connected. Hope this helps Alexander > On 11 Oct 2015, at 08:54, asma hamze <hamze2...@yahoo.com> wrote: > > Dear forum, > Can someone help with the construction a graph with program in GAP?A graph > fora group G, where its vertices set is G and two element x,y of G are > connectedif o(x)|o(y) or o(y)|o(x).
