I am working on some discrete mathematics and came across this strange operator on two sets.
$R \circ S$
I have only seen this circle operator with function compositions, so is this "Set Composition"? If so, then how does it work?
I found this on WebWork. The question is
"Suppose R and S are relations on a set A. If R and S are reflexive
relations, then R $\circ$ S is reflexive" select true or false.
