Lattice (ACE)
Let $A=\left \{ 1,2,3 \right \}$. A relation $R$ on $A\times A$ is defined by $\left ( a,b \right )R\left ( c,d \right )\Leftrightarrow \left ( “a\leq c “and” b\leq d “\right )$ S1:$R$ partial order S2: The poset $\left [ A\times A:R \right ]$ is a lattice Among S1 and S2 which one is true?

Kenneth Rosen Edition 6th Exercise 7.6 Question 54 (Page No. 525)
Determine whether each of these posets is wellordered. (Q ∩[0, 1], ≤) (the set of rational numbers between 0 and 1 inclusive) The answer is not well ordered because as it doesn't have any unique least element as 0 can ... /23,0/234). All are representing zero but there is no unique among them. Is this the reason here? Please confirm
