Question 1210200
.


The problem is posed/worded/ INCORRECTLY.


To be correct, it should talk consistently not about permutations, but about the sequences of integer numbers.  



Since it is worded in wrong way, I even will not discuss anything here.



It looks like the problem's creator does not understand the difference.


In such case, it is useless to make any explanations.


Simply, the problem's creator did not achieve the level yet, 
when such discussing can be productive.
