if you quote PW's post it turns out each line of symbols is separated, and does not break up into sequences of three symbols.
I was assuming it was done automatically by a word processor or for presentation rather than being meaningful in any way.

Theta, Omega, Wave, Triangle, and Phi.
The triangle is probably delta and wave is lambda :P
Been a while since I last saw you in an ER thread. Planning on having a crack at the cipher and rejoining with an AoW? :P

I decided to try using each character as base-5 numbers. Due to Java apparently not liking the greek alphabet I used MS Word to replace all the characters in my triplet sequence with letters from the regular alphabet.
Code: [Select]
Δ = A = 0
θ = B = 1
λ = C = 2
Ф = D = 3
Ω = E = 4

I then shoved it into the following tool I made:
Code: [Select]
import java.util.*;
import java.io.File;
import java.io.PrintWriter;
import java.io.IOException;

public class Cipher
{
public static void main(String[] args) throws IOException
{
String triplet;
int clearnum;
Scanner fileReader = new Scanner(new File("Code.txt"));
PrintWriter writer = new PrintWriter("Clearnum.txt", "UTF-8");

HashMap<Character, Integer> key = new HashMap<Character, Integer>();
key.put('A', 0);
key.put('B', 1);
key.put('C', 2);
key.put('D', 3);
key.put('E', 4);

while(fileReader.hasNextLine())
{
triplet = fileReader.nextLine();
clearnum = 0;

for(int i = 0; i < 3; i++)
{
clearnum += key.get(triplet.charAt(2 - i)) * Math.pow(5, i);
}

writer.println(clearnum);
}
fileReader.close();
writer.close();
}
}
This converts it according to the assumptions I made.

The result is as follows:
Code: [Select]

I hope it is somewhat useful for something. Even if that something is discrediting my triplet theory >__<

I found that if you analyze the text into bigrams, the resulting set is very roughly similar to the normal English character frequency, sans E.

Also, there happens to be 25 unique bigrams in the text. Index of Coincidence is 0.004 which means (1) this isn't a simple substitution cipher (2) I made the wrong assumption about how it is ciphered.

Not very helpful, eh? I doubt that this is going to be cracked quickly or easily :(

Yeah, considering that it can help unravel secrets, retrace another NPC's steps, and grants a 50-token bounty, it's probably going to take quite a while to solve it >__<

...what could be considered an equivalent cash prize?
Cause I'll do morally questionable things for the right amount of tokens that don't even exist RL.
Look at how much an avatar costs.

That much.

I tried to see if any of the lines were significant and if their size or whether or not they had odd or even number of letters depended on a letter or a combination of letters. That's as far as my notes go. May try a bit more letter:

Doing some research...

I think it's a vigenere cypher. Fuck me.

Then you should probably try "THE FLESH IS WEAK"

The problem now is finding out what symbol corresponds to what letter :P

Major things of import related to the Doctor: The 'Coordinates', 'Phobetor' who I must add was the reason the Doc got executed in the first place, and 'VonNost'.

Maybe one of them is (Or several) are a key word.

Considering this is most likely the same cipher the serial killer UE found, maybe try "the coming darkness" or something.

I'll look at the period, see if I can catch a good number in there.

I'm going with the assumption that it's a homebrew Cypher, something PW cooked up after one two many hours working on an update.

It's going to use a classical cypher, that's how he did it by hand.

Th problem is finding out the rules he used to crack it. Bluh.
