Journal of Integer Sequences, 18 (10), 15.10.4-1-15.10.4-16.1530-7638http://hdl.handle.net/11441/49018Given a subset A of the set {1, . . . , v}2 we say that (a1, . . . , av) exhibits pairwise coprimality over A if gcd(ai, aj ) = 1 for all (i, j) ∈ A. For a given positive x and a given set A we give an asymptotic formula for the number of (a1, . . . , av) with 1 ≤ a1, . . . , av ≤ x that exhibit pairwise coprimality over A.
