Question 5
(BRA 1) Consider the set of all strictly decreasing sequences of $n$ natural numbers having the property that in each sequence no term divides any other term of the sequence. Let $A=(a_j)$ and $B=(b_j)$ be any two such sequences. We say that $A$ precedes $B$ if for some $k$, $a_k\lt b_k$ and $a_i=b_i$ for $i\lt k$. Find the terms of the first sequence of the set under this ordering.
