Ha, Ha! Yes! I've cracked it!

there are more things in heaven and on earth horatio then are dreamt of in your philosophy

A slight misquoting of Shakespeare, Hamlet, Act 1, Scene 5. The line more properly reads:

Quote:
There are more things in heaven and earth, Horatio,
Than are dreamt of in your philosophy.

How I solved the code:

First off, as Brissyboy observed, most of the zeroes are indeed "red herrings": they actually separate letters. Replace all the zeroes with spaces, except where two zeroes are right next to each other, in which case only delete the one on the right.

Let's see what the first six words read, now...

2 26 13 9 24 9
5 8 27 12
1 17 19 23 8
0 24 11 12 17 9 23
4 16 21
7 18 14 10 33 14 24

Now, As trdhrdr observed, the first numbers of the first and fourth words are different, even though they're "supposed" to represent the same letter. That means that each word must have a separate decoding scheme. There's also one extra number in each word - that number must be the key to decoding each word and cracking the code.

Let's assume that it's the first numbers that aren't part of the word, since they always seem to be only one digit long. So let's look closer at the first and fourth words, particularly noting the first two numbers in the two words:

2 26 ... = t
0 24 ... = t

If you subtract the first digit from the second, you get the same number - 24. So that's the basic structure of the code: delete the zeroes, find the numbers for each letter, then subtract the first number from each letter-number t obtain a grand unified number. In this case, "24" is the letter T. After doing the math and deleting the first number, our first six words are now:

24 11 7 22 7
3 22 7
16 18 22 7
24 11 12 17 9 23
12 17
11 7 3 26 7 17

Now, you could try a simple number-to-ASCII translator to calculate what every letter should be, based on T=24, but if you try, you end up with garblage - nod2003 hasn't made it quite that simple. For now, we'll have to work out each letter individually.

So what do we see about word #1: it's five letters long, begins with a "T"... and the third and fifth letter are the same. I could only think of one word that matched: "THERE". It's also an excellent word to begin a sentence with. That gives me three more letters, H=3, R=22 and E=7. Our first four words now look like this:

T H E R E
? R E
? ? R E
T H ? ? ? ?
? ?
H E ? ? E ?

Now, the second word is clearly "ARE". The 12th word is, too. That gives us "A"; we now know that the ninth word, 4011070260280150, is "EARTH". We can also see the 11th word is "THE?" - and one can then reasonably guess that 17 = N, making "THEN".

So now the sixth word reads "HEA?EN". Given that we've already got "earth", it stands to reason we've got "heaven" too. So another letter goes into the matrix. Now, things are always "on earth" but "in heaven" - so that gives us "I" and "O". So now we've got:

T H E R E
A R E
? O R E
T H I N ? ?
I N
H E A V E N

Now, with just a few more logical guesses, and some extrapolation that seems to work, you've got enough of the solution for Mr Google to be of assistance.

The final number-letter code, as near as I can work out:

a 3
b 4
c 5
d 6
e 7
f 8
g 9
h 11
i 12
j 13?
k 14?
l 15
m 16
n 17
o 18
p 19
q 21?
r 22
s 23
t 24
u 25
v 26
w 27?
x 28?
y 29
z 31?

Nice job, Sap!

Your knowledge of coins, history and now this crypto exercise, makes me want to ask, "are you a member of Mensa?"

Nope, I'd be too slow.

It took me three days, from figuring out how to crack the code, to actually cracking it. A true Mensoid would've done it in minutes.

I'm not a member of Mensa even though I meet their entrance requirements & I didn't figure it out in minutes.

Well done Sap. I thought you might be the one to come up with the goods.
life is a mystery to be lived not a problem to be solved

I had the word "there" figured out, but was stumped from there. The first three words end in "re", but the numbers are 24-9, 27-12, 23-8, so I was having trouble extrapolating. I tried a Vigenere Cipher. I thought of a "play fair" but never saw a play fair using numbers. So I was still in the process of using addition and subtraction but just never got as far as Sap.

GREAT JOB!

Something as simple as subtracting the first number from all the other numbers.

My 250th post contest was a Vigenere Cipher.

You can see it here: https://goccf.com/t/43873

Once you have the key word, breaking it is fairly easy. It looks really complicated, but in the end, is quite easy.

Wow...nice work sap. I tried a similar approach as you, but when I looked at my worksheet, I apparently only copied about half of the code for some reason...lol. Congrats on winning.

Congratulations Sap, I came back today to get the next clue only to find it was solved already. Hummm, what happen to a clue on each 5th day LOL. Great effort there. I'm glad I at least worked out the 0 was mostly neutral.
