Henrick:
Graphs are composed of vertices and edges.
You are asking about converting a list of number pairs into edges.
First, don’t use “rule” to denote an edge.
Instead, use either Directed Edge or Undirected Edge .
These are typed <esc>de<esc> and <esc>ue<esc> respectively.
You have given the list {{2, 6}, {2 , 4}, {4, 5},{ 5, 6}} as example of number pairs
to be converted to graph edges. Here’s a few ways to accomplish that:
