Node list

Note that we do not need to repeat and list the edges "in both directions" since this is an undirected network. The same is true in the edge list:

Amir Bashir
Amir Danica
Amir Ellen
Amir Franke
Bashir Ellen
Bashir Franke
Bashir Gillian
Chastity Danica
Chastity Ellen
Chastity Franke
Chastity Gillian
Danica Franke
Danica Gillian
Ellen Franke

For the full matrix, we'll abbreviate the names with their initial letter. Note two things: (1) the diagonal entries (AA, for example) are zero; (2) the table is symmetrical around the downward diagonal. Make sure you understand why this is so.

_ A B C D E F G
A 0 1 0 1 1 1 0
B 1 0 0 0 1 1 1
C 0 0 0 1 1 1 1

E 1 1 1 0 0 1 0
F 1 1 1 1 1 0 0
G 0 1 1 1 0 0 0

For the directed graph we have:
