I have thought up one simple cipher. Hope it didn't exist before. Try to crack it!

Here is encoded one sentence in English consisting of three words.

$(2_ 2,5_ 2,7_ 5,8_ 5,9_ 4,14_ 4),(6_ 2,7_ 1),(3_ 2,5_ 4,30_ 4,70_ 2)$

  • Number with index corresponds to one letter


Numbers are not numbers

  • $\begingroup$ Do each number translate into it's own letter? $\endgroup$

    $\begingroup$ Decoding a cipher like this is very boring unless it has either a very clear direction to start working, or at least a full paragraph of ciphertext, preferably more. I do not want to spend an hour throwing random crap at your puzzle and checking whether the result is English. (Credit to @Lopsy for the copy-paste text.) $\endgroup$

  • $\begingroup$ @xnor I actually tried to disprove you for a while, but after that last edit, I do believe you are right. $\endgroup$

    $\begingroup$ I vote for re-opening, but I would like to ask Somnium to edit it with more information (not hints) to make it a better/solvable puzzle. I also think the additional encryption of the solution is not a good idea. $\endgroup$

    $\begingroup$ Nice one! This must be it. $\endgroup$ Dec 2, 2014 at 20:59
  • $\begingroup$ D@rn! I thought of part 1 right away, but part two never crossed my mind, so it didn't go anywhere! $\endgroup$
