Homework Statement
I have come across the following statement which I've written for myself a long time ago, and I don't remember what is going on.:
The adjacency matrix of R ◦ R is ##M^{(2)}##, where (2) signifies the square using boolean algebra.
Homework Equations
Boolean Squaring.
The Attempt at a Solution
Sorry for the potentially stupid question, but I've been researching how to compute ##M^{(2)}##, and the best I found was how to get an adjacency matrix from a graph, and computing ##M^2## (instead of ##M^{(2)}##).
If someone could either explain to me the ##M^{(2)}## part or point me to something that explains that, I would very much appreciate it!
