On S = f2; 4; 6; 10; 12; 20; 30; 60g we work with the divisibility relation R:
xRy , x divides y:
(i) Draw the Hasse diagram of R.
(ii) Find all R-minimal elements.
(iii) Find all R-maximal elements.
(iv) Find all non-empty subsets U S, so that 6 is an R-lowerbound of U.
(v) Let A = f6; 10; 12g. If A admits an R-supremum, nd it. If A admits an R-in mum, nd it.
(vi) Is R a lattice?
