3 or more undirected nodes

[sonji12461]

Hi, i have some question about setting CSV data for GEPHI.
i'm trying to analysis about the keyword from various paper.
the keywords are extracted almost 3 or more from one paper.

i know how to set the CSV data for 2
(one will be source, another will be target, and type will be undirected)
but i don't know how for 3 or more.

for example,
there's 5 keywords, A B C D E,
i tried to separate pair but it is different depend on order.
(ABCDE is different from ACEBD, but there's same keywords)

if i make pair for all probability(AB, AC, AD, AE, BC, BD, BE, CD, CE, DE)
it looks so heavy(?).. is it right way? or not?

have a nice day! tnx!
