Coned off graph
I removed the following sentence:
" If H is a normal subgroup then the coned off Cayley graph is the same as the quotient graph of Γ(G) by the action of H. "
as it is wrong. It is probably correct to say that in this case the coned off Cayley graph is quasi-isometric to the quotient graph, but it is certainly not the same. (Consider the case H = G.)
