When I enter for example
G = Part[GraphData[10],1];
LG = LineGraph[G];
I get error message that LineGraph requires a graph object.
How do I convert G into an object accepted by LineGraph? I am using version 9 of Mathematica without Combinatorica explicitly loaded. No doubt a very simple question. Thank you.
You are trying to get at the graph {"Antiprism",5} since you get:
G = Part[GraphData[10],1]
(* Output: {"Antiprism",5} *)
After that, you actually need to use "LineGraph" as an argument for GraphData as:
GraphData[G, "LineGraph"]
That should give you the line graph of your G.

Wrap it with GraphData:
G = Part[GraphData[10], 1];
LG = LineGraph[GraphData@G]
