53v4 has finally been solved. 'Twasn't easy.

Spoiler (Rollover to View):
First of all, you have to use a vignere program to get letters into a solvable state. nivra found that omaauglpsiwe works the best. Next you have to swap pairs of letters, carrying over the line breaks (RC NE HS will become CR EN SH). Numbers do not switch. This will give you about 90% of the streets. For any streets that are still messed up, you need to do a ROT-1 on the messed up pairs of letters.

The list is really long - so please go to the wiki.

Credit for solves goes to: nivra, Rowan, misssphinx, Diandra, catherwood, and others


An interesting list... Just following the trail of the crossroads and addresses that include Pico, it appears as there is a "stop" every couple of blocks... So that means that these are leading us to one of two things...

Bus Stops or Starbucks Locations. Smile

Great Solve - how did the clue fit in with it?

Is there a list of the addresses that had to have the additional step used on them? Maybe those are more important for some reason. I don't understand why a puzzle would be designed to require so many steps if there is no substantive reason for it. Otherwise most of these puzzles seem like buzy work.

We don't know, actually. I never was able to decipher the clue into
anything useful. Much like the other clues, it probably would have
given us some lead into the vigenere key or the "214365" de-anagram.

Check the wiki. The addresses that needed a ROT adjustment are given
in their original de-anagramed form with the rotted correct address in
(parentheses) next to them. Note that sometimes the pair of letters needing
to be ROT'd crossed line breaks.

Well, I think the puzzles are getting harder. More ciphers, harder to keys, et\
c.

When I get a chance, I'm going to look back over the pairs of letters that need\
ed to be ROT'd and see if there's any discernible pattern. After all, a ROT-1,\
is also just a vigenere cipher that's offset by one character.

 		I'm still not convinced this one was Vigi.
Maybe rolling ROT or something else.
It just seems it was shoehorned into Vigi.
Of course, it's solved, so...

I might be wrong, I'm not that up on Vigeneres, but isn't a rolling ROT technically what a vigenere is? You're just using the keyword to determine what the shift is for any particular letter. I could encode a passage using ROTS of 8, 5, 12 & 16 repeated again and again or I could just pick a keyword thats easier to remember. I was at first thinking that the number would correspond to the shifts, but I wasn't able to see how. It does bother me a little bit that we don't know what the clue was for.

The "21436587" anagram pattern can't be part of a ROT or vigi. There's just no way for either of those two encoding methods to do this type of shift. So, there's at least two parts of the cipher: 1)ROT/Vigi 2) anagram.

This agrees with my understanding of a Vigi. Of course, I just started learning what either of these two are since I started Heist, so I'm new to encryption.

I looked at that, too. No luck. I guess this is another minor "backsolve" up for grabs. I'll look at this later, too.

 		Solved 33c4
Okay, here are the addresses for 33c4... someone can double check them, because I want to make sure I didn't mess up:



Spoiler (Rollover to View):

Franklin & Howard
Girard & Broad
Girard & Ridge
15th & Ridge
16th & Ridge
1637 Ridge
1536 Ridge
1113 Race
1239 Broad
2400 Broad
7th & Girard
Buttonwood & Nectarine
1112 Broad
1309 S 34th
534 Washington
3468 Kensington
Front & Emerald
11th & Cherry
1017 Arch
122 N 13th
1200 N 52nd
238 n 50th
4457 Main
Main & Green Lane


The text is written all on one line, but in the middle appears "><"

I took this to mean a break/mirror image point. If you start with the first letter in the text which is an "F" and then go to the last letter, you get "Fr." Then you go back to the 2nd letter and get "Fra." Going to the 2nd to the last letter of the text you get "Fran." I just kept following this pattern and got the addresses. This is also why it'd be nice for someone to double check the addresses as correct.

Not sure what city it tracks back to, but it looks like Philly, although some street names I recognize as being in SF. Confused

[EDIT]: Looking at the city at maps.google.com, I think it's clear this is a solve for Philly!

And Nivra double checked the addresses, and they look good. Thanks, Nivra!

I recruited my husband and his mad skillz to plot out some cities. Boston is attached and below are the lat/long coordinates. I don't see any particular pattern or anything, but let me know if you want more cities.



Missphinx, any way to get maps of the other cities? I think the visual representation showing off the locations might help us to what the addresses may have in common.

Give your husband mucho thanks.

 		87s7 solved
Don't know what the key means. Check the spoiler for solve.
Spoiler (Rollover to View):
This one is a vigenere cipher, key LJKUNLJA, and then a straight substitution.

2680 HARRISON ST ( I )
3045 SHATTUCK AVE
2680 HARRISON ST ( II )
510 7TH ST
58 COLLINGWOOD ST
1850 CESAR CHAVEZ ST
529 28TH AVE
1321 MISSION ST ( I )
1635 MARKET ST
1321 MISSION ST ( II )
275 SAN CARLOS ST
1415 HAIGHT ST
2467 HARRISON ST
1590 FOLSOM ST
3262 MARKET ST
1971 FILLMORE ST
877 CORBETT AVE
1865 LOMBARD ST
6199 3RD ST
1236 19TH AVE
657 VALENCIA ST
1850 19TH AVE
671 NATOMA ST
4109 IRVING ST
3522 20TH ST
645 27TH AVE
1745-55 MARKET ST
574 2ND ST
1401-53 MARKET ST ( I )
522 2ND ST
1401-53 MARKET ST ( II )
4071 18TH ST
699 3RD ST
1179 MISSION ST
2963 MISSION ST
485 NOE ST
117 MASON ST
1328 POLK ST
4051 SAN PABLO AVE
2322 PINE ST



I found the vigenere length first, by looking for repeated sequences.
For street endings, there are 8 "KH", 6 "IY", 5 "MJ", 5 "JS", 4 "TL", 4 "ZJ", 1 "II", 3 "BQA", "EHW", "LJY", and "AGH".
For #xx endings that should map to "th", there are 4 "JT", "LV", "YV", "IE"
For #xx endings that should map to "rd", there are 2 "NZ"
For #xx endings that should map to "nd", there are "OI" and "PX"
If you consider only the repeat ones, an 8 character vigenere cipher leaves all repeats IN PLACE, except for "KH": of the 8, 6 map into one pair, and 2 map into a second pair.
So the length=8.

Then I solved for each character in the key by mapping known letters for internal consistency. Internal consistency comes from knowing the answers to #xx streets, like 3rd and 2nd both end in "D", so they have to match on the same letter for the sub, and knowing that all the numeric streets in san francisco end with "st" or "ave", therefore "IY", "ZJ", "JS", and "MJ" all map into "ST." I also mapped 20xx, 17xx, 19xx, all into the same matching characters, that matched the above "ST."

Then, it's a straight sub.

[UPDATE]The vigenere cipher rot's into CABLECAR, which presumably is the correct vigi cipher we should get from the hint "interface ellis tryst." Since we're doing straight sub, afterward, any Vig key that's a ROT of CABLECAR will work.
After CABLECAR ROT: the Straight Sub key becomes:
AZYXWVUTSRQPONMLKJIHGFEDCB
(I think, I only ran the first 5 letters)

Awesome work, Nivra! You have a lot more patience and skill that I. Very Happy

I'm going into SF today, so I'll be sure to check out what addresses I can. I notice some of the streets are in Berkeley too.

The closest we could come with that clue to the key was that it anagramed into "STREETCARS FINELY LIT." Although, maybe something was missed.

 		Confirmed 1 poster in SF
I'm in SF with a friend and while she's shopping, I've decided to take some detours to the newly decoded SF addresses... I've confirmed the 2322 Pine St. one. Looks like same VIN too.

 		I mapped out all the SF addresses in MapPoint (could post the file if wanted). There are two "flyers" out in the east bay, but they could match up to sf addresses that just weren't in the database. There are a lot of points to plot, so the map is a little hard to make out. Hopefully it'll be usefull for something. If we get anything outa it i could do the other cities. I also ran a driving directions map, that will probably be useless, but i've included it too.

 		If all the addresses don't have the flyer, maybe we should just map the ones that do? Alot of places to check though, so I'm not sure if this is what is expected of us. Wouldn't want to be the one person in a city following this game that has to check 20 or so locations.

 		Wow - great solving!

I'll scout out the two in the SF East Bay. (Yay)

We can probably do some more city mappings later today.
