Suppose, $A$ is a well-ordered set with strict well-order $<_A$. Suppose $B$ is the set of all bijections from $A$ to $A$. Let’s define a relation $<_B$ on $B$ in the following way: $b <_B a$ iff $\exists c \in A$, such that $b(c) <_A a(c)$ and $\forall d <_A c$ $b(d) = a(d)$. Is $<_B$ always a strict well-order?
I know that it is always a strict total order, because it is both transitive and trichotomous. If $A$ is finite, then it is also a well-order. But what is about the general case?
OK, this is simply the lexicographic order on the permutations of A.
Say, A is the set corresponding to the ordinal $\omega+1$, that is, $A=\{1,2,3,\dots,\omega\}$. Now consider the following infinite series of permutations: $$\begin{aligned} a_1=&[\omega,2,3,4,\dots,1]\\ a_2=&[1,\omega,3,4,\dots,2]\\ a_3=&[1,2,\omega,4,\dots,3]\\ \vdots\\ \text{etc.} \end{aligned} $$ etc.
Clearly each $a_i$ is smaller than the previous, but where is the smallest element?
