The document contains definitions of several sets and relations. It defines sets of numbers like A = {1, 2, 3, 4, 5} and relations between elements of sets like R = {(x, y) ∈ A × A / y is a multiple of x}. It also defines relations using logical conditions with operators like union, intersection, and difference between relations.
