%e A181852 Example: The ninth member of A094348 is 60 because lcm(1,2,3,4,5) = 60. Let H(n) = Sum_{k=1..n} 1/k. Since H(60) + exp(H(60)) log(H(60)) = 170.9766843.. and sigma(60) = 1 + 2 + 3 + 4 + 5 + 6 + 10 + 12 + 15 + 20 + 30 + 60 = 168 it follows A181852(9)= 170 - 168 = 2.
%e A181852 Further, the inequality 0 <= A057641(lcm(1,2,3,4,5)) is in agreement with (Lagarias' formulation of) the Riemann hypothesis.
