The book is a road block for me without it I can't go any further .
I'm in a non English country .
English books are rare in bookshops  over here .
Ordering online take ages to deliver to my country .

As for brute forcing it's not fun at all.
And useless anyway at this stage especially if there is a reordering step.



5 days left till end of puzzle.
I hope the OP is preparing another one.
