Yes if you could find the "KEY" that these letter substitutions came from?
Well, the characters from your page 3 seems to have pattern...though My head hurts after studying for about 8 hours...There seems to be a pattern but I am not sure..
for example, Number 107 you said it was R....The 107th word in DOI is (Happiness)...Take out the last word (S) then subtract 1 letter, it will become (R)..
Number 78 you said (T), in DOI the word is Self, then I take out the first letter(S) then add character so it becomes (T).
Its like taking out the first & Last word then add or subtract characters...
Also I noticed, Sometimes you take out the nearby character BEFORE or AFTER the number..Sometimes add or subtract them with 1 character works..
This is weird, as if there is really a specific pattern in each set of numbers.
I still cant figure this out...but there is something going on.
Ill let you know soon.
