ROUND 2, CHALLENGE 1: The Marketplace
Today, you will be going to the market. The commodity, and the currency, is INFORMATION.

I have created a 15-digit number abcdefghijklmno. You just need to let me know what this code is. Heck, I'm even going to give you more than half the code!

The catch? I will be giving each team a different portion of the code, specifically 8 digits of the code.
Of the 15 digits in the code:
(a) 1 will be given to all 4 teams
(b) 4 will be given to 3 teams
(c) 6 will be given to 2 teams
(d) 4 will be given to 1 team
Stated another way, each team will possess:
(a) 1 digit which all 4 teams have
(b) 3 digits, each of which 2 other teams also have
(c) 3 digits, each of which 1 other team also has
(d) 1 digit which no other team has
These will represent all the combinatoric possibilities -- so looking at category (b), there will be one number owned by teams 1, 2, and 3; one owned by 1,2,4; one owned by 2,3,4; and one owned by 2,3,4.

You will know only what your digits are (and which position they correspond to). You will NOT know how many or which other teams have each of those numbers. Obviously, the digit which only your team has is worth far more than the digit every team has.

I will also give each team a unique order in which to post their results, so that they may be publicly posted without giving away all the solution. For example, I might tell one team to post the code in the order lbdehagcominfjk. This code will also be contained in the private message each team member receives, described in the next paragraph.

I will start a new thread titled "Survivor: R2C1 - The Marketplace". Solutions may be posted in this thread. You may also use this thread for any public dealing you choose to do. At 11:00a ET, I will post "BEGIN CHALLENGE" in that thread. At the same time, I will send each of you a list of your team's digits and the encryption code to be used for your solution. I will send this message from the "Trading Desk" ID I have created.

Here is a sample of the PM you will receive

These are your team's codes for Round 2, Challenge 1: The Marketplace
a=2
b=6
d=1
f=7
i=0
l=4
m=3
o=9

Please post your code in this format:
kjneohdlgaifcbm

Once you have managed to bargain with other teams for their piece of the puzzle, post the code, using your team's unique format, in the thread I will start titled "Survivor: R2C1 - The Marketplace". For example, our solution post should look like

Teamname

372698143207563

No edits allowed or the post is disqualified, and considering you would have already given away valuable information, this would be a very bad thing for your team.

You may barter however you wish for the other team's information. Your may deal in misinformation. You MAY deceive another team about how many, and whose, pieces you have. You may NOT commit to swapping digits if you do not actually have them, and you may NOT give false digits (e.g. tell them g=1 when actually g=3). To enforce this, I have set up a "Trading Desk" ID. All transactions must go through that ID. Once you have finalized a transaction, each party should send a note to the "Trading Desk" ID, describing their side of the transaction and to which individual they wish to pass that information. For example, Will Durant could send a note saying

Give h to Jables; I get a back

I would expect a similar note from Jables. Depending on your deal, there might not be an equal swap, or any swap at all. A player might make a side deal, and give away info with nothing in exchange

Give h to Jables

I will not question any transactions. Nor will the details of a trade be made public until the end of the game. This will include the team, individual, and information involved.
Note that information is traded between individuals, not teams. What information you share with your teammates is at your discretion, including both information you have received and information you have disseminated. I will NOT confirm to a player any transactions in which they were not involved.

You may bypass the Trading Desk if you wish, but you do so at your own risk. The Trading Desk is the only verified source of information. Doing your own "direct-party" trading could be faster, but has its risks as well.

When you wish to do so, post the portion of the code which you know. Results should be posting in the "Survivor: R2C1 - The Marketplace" thread I create. Scoring will be based on #correct digits, followed by order of posting. There will be no penalty for incorrect digits, so as with the actuarial exams (maybe just on the SOA side?), guess if you need to do so. Both individuals and teams may make multiple posts. This would allow you to update your solution if you get new information (extra information beats speed in the tiebreaking category). You may, of course, post only when you have the entire code, should you wish. Only the most recent solution posted by a team member before the challenge ends will be counted. Solutions will NOT be confirmed prior the challenge ending. Any team failing to post a solution at all will score 0 points.

I will answer any questions on this challenge either by PM or public post. If you have a question you feel may give you a strategic edge, please ask by PM - my response may either be by PM or public post, depending on the nature of the question and response.

Excuse me, but anyone who has passed Course 1 knows that there are 2^4 = 16 combinatoric possibilities. You need a 16 digit number, with one digit given to no teams, only the mole. I trust that by 11 you can come up with more more digit. Pillow is good at generating random numbers if necessary.

The Mole's Trading Desk will open shortly after 11. In a special opening day offer to generate repeat business, the mark-up will be very low. You give me 8 digits. I give you back the other 7 as soon as I get them (with individual digits being delivered as soon as they arrive).

I expect everyone will want to take advantage of this great offer. If not, I may not get all the digits you want. But you cannot lose by trusting the mole. If I don't send you all 7 missing digits before the contest is over, you get all 8 of your digits back. I keep nothing for expenses or profit.

Act fast! This is a FIFO offer to individuals. E.g., if aces219 sends me her team's digits, which don't include a, and J.T. sends me the same digits, the first a I receive goes only to aces219.

(Free to the first 9 customers: the 16th digit that ury will be giving to only me.)

Clarification: The game in question is the entire Survivor game, NOT just this challenge.

Worth repeating. The post is rather long, but I want to stress this piece
You MAY deceive another team about how many, and whose, pieces you have. You may NOT commit to swapping digits if you do not actually have them, and you may NOT give false digits (e.g. tell them g=1 when actually g=3).
Just because the Trading Desk is available as a verifiable middleman does NOT mean the ethical restrictions of this paragraph are weakened.

Clarification: The Trading Desk can only deal in commodities it knows your team has. If you have worked out a private transaction to get "h", for example, you cannot then ask the Trading Desk to "give h to PlayerA". If you think this could be a concern, be sure to have you and your trading partner also confirm the transaction through the Trading Desk.

BEGIN CHALLENGE - The Trading Desk is now open

I will PM each player its teams codes, starting with the team captains.

Because the best markets are efficient markets with free flow of information, I will be posting the digits I have available as soon as I learn them.

Digits known (not in order)

Positions known (Y= that position is known)
abcdefghijklmnop

Warning: the previous post is not correct. Several clients have now supplied values, with no inconsistencies among them, and with some at variance with the ones I originally got from Ebenezer Kohl. They have asked that I not update the list, and I will not violate my clients' trust.

This game will be over very soon if a trustworthy member of Channel 4 News comes to Mole Trading.

I appreciate your business, but Mole Trading normally deals via PM. BC and J.T., let me know if you want that 16th digit that only I know. Sorry, cubedbee, the free offer of the 16th digit was only to the first 9 customers.

Hey ury, I guess we are way faster than you thought. That took less than 1.25 hours.

The Trading Desk has closed early for the day. All posted solutions are correct, and I'm going to make the executive decision that nobody is going to be silly and go changing around their answers after the fact.

Final order of finish for this challenge:
Team Fark -- 4 points
Stone-Age Variables -- 3 points
Scheme-in-Training -- 2 points
Channel 4 News -- 1 point

Wow, you all finished that much faster than I had expected! Guess we'll have to make sure the next one isn't quite so easy :D

Free enterprise works. Teams used the most efficient trading environment.Team Fark -- 4 points
Stone-Age Variables -- 3 points
Scheme-in-Training -- 2 points
Channel 4 News -- 1 point
Four finishes so close together. Congratulations to Team Fark, who realized Mole Trading's FIFO service meant they should sign up early.
