Feels like I’ve tried everything but still can’t find a way of grouping it so that the trigrams mean something to the telegraph. Definitely saying “There is a key feature of the symbol groupings that considerably reduces the possibilities” is not saying too much, I still feel clueless. As said above, rearranging/transposition has too many possibilities and there are no easy to spot patterns that eliminate most possibilities (at least that anyone on here seems to know of). This isn’t even the hard bit – deciphering the actual cipher once you’ve grouped the trigrams is the hard bit, yet many of us are still stuck here 🙁
A New Year promise: We will try to be a bit less obscure from 3rd Jan 2025! But for now, it is time to PARTY! Happy Hogmanay, Harry
I am going to suggest to all the confused rabble out there that they might try finding the smallest block that always contains the same number of / and \ and |.
Dear Harry,
Do you mind helping me by telling me if I am on the right track with 10B?
I know what the cipher is however, I don’t understand what the groups of 3 with arrows that aren’t pointing the same direction mean ( e.g. ///, \\\, |||, //|, ||\ etc… ). So I thought I can just get rid of all of them?
Can I do that and is there another step after that?
Thank you very much! ( I have thoroughly enjoyed this challenge, so thank you and the team for all the fun! )
I am afraid this is not the right track. Every symbol plays an important role throughout the text. If you read the hints and replies we are publishing here on the forum you might get an idea of what is going on. Harry
@ILL Most helpful cases were for me 10.7 and 10.8. If you learn enough about 10.8 then you can maybe understand better 10.7. (please censor or dont publish this message if it’s too much)
Case File 10.2 well that really dd tell me a lot, no seriously, for one it suggests that we are probably staying with a three needle code
and that the three needle patterns do, more than likely, need to contain only 1 of of each type \, |, /.My thoughts, [HARRY REMOVE ANY/ALL OF FOLLOWING IF YOU WISH]
BUT with the code starting with \\/\/, ||\||, \|//|, |/\ etc. and changing to blocks of three gives \\/, \/|, |\|, |\|, //|, |/\
clearly not giving proper groups, this suggests that manipulation of the code is needed in some uniform way.
Having tried quiet a few ways, I still have some ideas yet to try out.Mistyped, I mean a 21-charactered “brick”
Zgrb, Yes I did know of what 10.8 is saying for a while. What I don’t understand is how to transpose all of the characters in order to get them to be in a 1:1:1 ratio per 3. I know the count that first gets it to be all of them in 1:1:1 [7:7:7], but nearly all of the transpositions I’ve tried [that were Tabular and Columnar] have not come out with anything with bigrams less than 36, and I cannot seem to understand what the bricks mean.
-ILL
I have done that, and tried transposing, but can’t seem to find an order which works for all rows of 21. Am I on the right track?
Harry so far i have removed all chunks that don’t contain 1 of each symbol and i have now substituted each chunk to the letters A, D, F, G, V, X based on their arrangement in 10.8. [Edited by Harry]
Definitely do NOT remove anything! Every character is important! Harry
(Harry: I have tried to be a little cryptic, but I do not know if it is too early for discussion about the key.)
Following on from Case File 10.8, I have been wondering about the key to 10B. It had me going round in circles for a bit, but I think I have it. However, it does not quite seem consistent with Case File 10.8. [Edited by Harry]Since the cipher you allude to had not been invented at this point, it would be surprising if the assignment was that accurate! Think of 10.8 as pointing you at the broad structure of the cipher rather than the details and you should be fine. Harry
It’s been over a week since I did what Madness suggests. I have blocks of 21 symbols, but even so, I can’t seem to rearrange them. My sprint stopped at 10A. I can’t get over the last hurdle.
Challenge 10B was never going to be a sprint. More like a marathon, or, as you suggest, perhaps a steeplechase! Don’t give up, more hints are on the way from other competitors. Harry
You are on the right track ! Just have to find the right reordering… Some logical thoughts can help !
@F6EXB
Try looking for sets of three that are always different in each block.If the ADFGVX cipher wasn’t invented until 1918, then it can’t be that – so why is 10.8 alluding to it. Also after splitting the text into chunks of 21, i cant seem to rearrange them in the correct way, am i missing something?
To be clear, just because a cipher was actually invented a bit later doesn’t mean we wouldn’t use it. The very first National Cipher Challenge featured a simplified version of the Enigma machine. The rule is broadly that if our protagonists could reasonably have invented a cipher of that form, then they might have done. But to be equally clear we usually change things a bit to keep them interesting (and doable, we hope!) Harry
oh my god i want to cry im done with 10B finally
I SWEAR TO GOD I LITERALLY CONSIDERED THE CIPHER AFTER 3 DAYS BUT DIDNT TRY IT BASED OFF OF HOW SIMPLE IT WAS
I DID THE SAME THING WITH 9B I HATE MYSELF
In all seriousness though, 10B was incredibly fun, despite me wanting to tear a hole through my computer.
To those still struggling, I will say (hopefully Harry allows this):
You should really look at _madness_’s post in this topic, and consider previous challenges.Good Luck!
