It's nice to see your efforts to find the code.
I insist on the fact that no math is needed. Just carefuly look at the book preciously to find the number.
So, to resume as Malachi said :
1/ Find why p11 #10 give the letter "t"
Check the rule with p54 #32 give "a"
2/ When you inderstand the first rule, Find all the other number. It's so easy when you discover this rule ! The dots are here only to check if you are on the right or on the wrong way.
3/ Then, with the first rule, find all the others letters and read the word.
yes it's a french word but finding the rules, you will not have problem to find it ! And no, it's not "Tanteidan" !
Then send the code to me !
In order to give you more motivation, I've just add a new exclusive diagram in this secret section.
Who will be the first to crack the code !
