In this paper, we proposed an interesting problem that might be classifiedinto enumerative combinatorics. Featuring a distinctive two-fold dependenceupon the sequences' terms, our problem can be really difficult, which calls fornovel approaches to work it out for any given pair $(m,n)$. Complete or partialsolutions for $m=2, 3$ with smaller $n$'s are listed. Moreover, we have provedthe necessary condition for $p(m,n) \neq 0$ and suggested an elegant asymptoticformula for $p(2,n)$. In addition, several challenging conjectures areprovided, together with concise comments.
