I have what seems to be a simple question about interlocking networks,
but I'm having trouble coming up with a straightforward answer. Any
suggestions would be much appreciated.
Given a two-mode person-to-group network X, it is easy to obtain a
one-mode person-to-person network Y. Namely, Y = X * X' (see Breiger
What is the smallest number of groups in X that can produce a given
network Y? And, relatedly, what features of Y influence how many
groups are needed in X.
